AbiWord text cursor starts to flicker after adding some text

This bug has been reported on the Ubuntu Package testing tracker.

A list of all reports related to this bug can be found here:
http://packages.qa.ubuntu.com/qatracker/reports/bugs/1574278

I am experiencing the same problem on three laptops... Abiword flickers when either starting and typing some text or when opening an existing document.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same issue

Ditto with 3.0.1-6 though someone reported in Arch the problem went away with 3.0.1-5 ( https://bugs.archlinux.org/task/46659 )

I stumbled across a discussion on this in #lubuntu-devel on IRC.

I'm setting "Medium" importance on this for several reasons:
* This package is part of the lubuntu-desktop task. This means it's considered part of the Lubuntu Desktop core software set.
* This package is in the Universe repository. For general Ubuntu triage, Universe equates to Community Supported
* Based on the changelog and package history, the package has not had any updates to actual software since Vivid.
* Upstream, in Debian, the package is considered *orphaned* and has no maintainer. This has been the case since 2014.

There can be an argument made for both High or Medium - I however believe Medium fits better in this case. (This can be changed in the future if a stronger case is made for "High", or more triagers consider this to be "High" than "Medium" in this case)

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=740678 is the Debian Orphaned Package bug on this.

I have confirmed this, however it is *only* the cursor, it is not the text itself or other components - it is only the cursor. This doesn't impact anything but that cursor blink rate.

I can only replicate as reported by the OP when I start triggering automated scroll downs. Pasting 15 pages of filler text was able to very quickly trigger this issue.

It actively impacts usability, so I'm bumping this to "High" actively (you can't see the top third of the document window through the flickering interference).

Can confirm this bug after Upgrade from Lubuntu 14.04.4 to 16.04.
(abiword 3.0.0-4ubuntu1.1 -> abiword 3.0.1-6)

As soon as text is added, the cursor begins to blink unsteadily.
Also, Abiword then begins to use unusual amounts of CPU (not enormous, but a few percents). When minimized, there's no CPU-usage anymore.
When there's more text added, the whole documents starts to flicker, especially the background. This effect can be lessened by shrinking the Window, zooming in the document or setting focus on another window (so the cursor doesn't blink anymore).
The bigger the window and the more characters displayed, the more flickering and CPU-usage.

System: Intel i7-2670QM with integrated HD3000 Graphics.

I was reading some post on the Arch site and it seems compiling with GTK2 rather than GTK3 resolved the problem. I just build 3.0.1-7 package from source on my machine (using GTK3). The flickering issue seems to be down to just the cursor but I have some other build issues I need to look into.

FWIW the latest update is causing a conflict with libtidy on my system. Abiword want's the old libtidy-0.99-0 but the new libtidy5 (1:5.2.0-1) want's to have it's libs installed in the same place with the same name. As a temporary fix I uninstalled the old libtidy, installed the new libtidy5 and libtidy-dev. The only compile issue I ran into is ./configure looking for tidy/buffio.h wich is now tidy/tidybuffio.h. I just created buffio.h and linked it to tidybuffio.h. To get it to compile, do not know the consequences of doing so yet.

As I said before I have some other build issues I have to address, but I do have the program up and running, don't want to hijack this thread with it but if anyone is interested please contact me.

I confirm this issue on two Lubuntu 16.04 fresh installs. I could correct it.

First yesterday on a Core2 Duo laptop I installed the OS from the official lubuntu-16.04-i386 image.
As OP writes

> After adding some text in a new document, the *entire document* (including gray page background, text, text cursor) starts to flicker very fast. The UI above does not flicker.

Adding even a single letter has the whole content area to constantly flicker. We could reproduce this anytime launching Abiword.

Second occurence was today in a qemu-kvm VM with lubuntu that I freshly installed from Ubuntu mini/netinstall ISO.

- Opening an existing odt document has the header constantly flicker, i.e. the top 4 centimeters high banner.
- Opening Abiword (blank) and write any number of letter has the top 4 centimeters high part of the document constantly flicker.

Here is how I could correct this wrong behaviour:
- Launch lxappearance, in 'Widget' tab shift to any other one than 'Lubuntu-*', apply.
Abiword stops to flicker.

Thanks to William Geiger and Arch posters for bringing up the gtk3 settings.

I can duplicate this bug easily by installing lubuntu-artwork and setting my gtk-theme to either of the 2 Lubuntu themes.

William, no I don't think abiword will be reverted back to gtk2 in Ubuntu.

Antony from #6 , Arch's 3.0.1-5 is just the 5th Arch version of Abiword 3.0.1; it's not the same as Debian or Ubuntu's 3.0.1-5.

Status changed to 'Confirmed' because the bug affects multiple users.

From the following post at the Ubuntu Forums, I conclude that it is a problem of the Lubuntu desktop environment.

Interesting observation. I tried with a current (up to date) Lubuntu 16.04 LTS installed system.

Abiword flickers in a Lubuntu session.

But at the login screen I can also select Openbox (only the window manager, no fancy desktop environment).

Abiword does not flicker in an Openbox session.

The difference is very obvious and repeatable. I need not reboot, only log out, switch session (near the top right corner) and log into the other session.

I used the following command to test Abiword (3.0.1-6ubuntu0.16.04.1) in Lubuntu 16.04 (upgraded from 14.04 and fully updated) and in Lubuntu 16.04's Openbox session:

GTK_THEME=Theme_name abiword /usr/share/doc/abiword/copyright

The themes I tested were:
Adwaita (installed by default)
Adwaita:dark
Ambiance and Radiance (from the light-themes package)
Greybird and Numix (from the shimmer-themes package)
Lubuntu-default

In my system, both Lubuntu (LXDE + Openbox) and Openbox, only Adwaita and Adwaita:dark were flicker-free. With all the other themes listed above, there was an approximately 4 cm tall, screen-wide area that flickered shortly after the page loaded. The flickering did not affect the UI and didn't seem particularly related to the cursor.

My system is a Dell Inspiron 1545 laptop (Core2Duo, 4GB RAM, 64-bit, no GPU)

Augustine Souza alias vasa1 at the Ubuntu Forums found the workaroud:

*Change to the gtk theme Adwaita*

when it is available.

I found that several other themes work too without flickering (but not Lubuntu-default and Lubuntu-dark-panel).

Some of these themes render the text black in black background for marked text, others render the text dark but visible.

-o-

Workaround in a system directly from the current Lubuntu Xenial i386 iso file:

Start Abiword and edit a file. If it starts flickering, select

Menu -- Preferences -- Customize look and feel

- Select another theme alias 'widget style'

- Press the button 'Apply' and watch what happens in the Abiword window. Edit and do things to check how it works with this new theme, and stay with a theme that works for you.

For example the first one in the list, Clearlooks, works for me in a Toshiba laptop with Intel graphics from 2013,

http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/

and in a desktop with nvidia graphics from 2008,

http://www.asus.com/Motherboards/M2NVM_DVI/

-o-

In Xubuntu Core, which runs the gtk theme Greybird by default, the cursor was flickering (no strips), and it was fixed by selecting the theme Adwaita, like by Augustine Souza in his upgraded Lubuntu system.

Impacting OLPC.

Reproduced using Ubuntu 16.04 Xenial amd64 iso booted as live-image, plus universe, with abiword_3.0.1-6ubuntu0.16.04.1 from xenial-updates.

Workaround: switch from Ambiance to High Contrast theme.

Also affects package sugar-write-activity_97-5 which depends on package gir1.2-abiword-3.0 and thus libabiword-3.0. In my testing, the draw signal from Abi.Widget is constantly emitted by Gtk as soon as the first text is added to an empty document. The consequent Gdk redraws cause cursor and screen flicker, the severity of which scales with window size, graphics card, and CPU performance.

Related bug https://bugs.sugarlabs.org/ticket/4915 for abiword 3.0.1 on Fedora 24 combined with the Sugar Write activity.

So it would seem this is a problem introduced in Gtk or Abiword. I'm available to collaborate on this problem at depth. Contact <email address hidden>, thanks.

Raised upstream as http://bugzilla.abisource.com/show_bug.cgi?id=13791

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:
http://iso.qa.ubuntu.com/qatracker/reports/bugs/1574278

This effects both the version that ships with Lubuntu 16.04 (abiword 3.0.1-6), and the latest version in lubuntu repositories (abiword 3.0.1-6ubuntu0.16.04.1).

I would be happy to test improvements.

This bug renders Abiword unusable it is so distracting and nauseating to look at.

Confirming for Xenial (16.04.1),
Package version: 3.0.1-6ubuntu0.16.04.1

According to upstream bug, it's a gtk 3.18 bug which Abiword triggered. An update to 3.20 fix the issue, which is the case on yakkety. To fix the bug on 16.04, we have to find the correct gtk fix (which may not be that easy).

Status changed to 'Confirmed' because the bug affects multiple users.

Using Xubuntu 16.04 with all updates here.

I can confirm both the original flickering and the effectiveness of the work-around "GTK_THEME=adwaita abiword".

Yes, but we can't force an app to use a custom theme, modifying all Ubuntu
distros as a workaround, instead of actually fixing the problem. Apps must
use any theme.

  I can confirm [...] the effectiveness of the work-around "GTK_THEME=adwaita abiword".

With some more testing I have to qualify that statement a bit: With the adwaita theme the behaviour is clearly improved compared to the default. I have not seen text flickering so far. But the cursor still flickers a bit and sometimes disappears completely until some new text is entered.

Uwe, do you have a method to reproduce flickering with the GTK_THEME=adwaita?

Even so, the workaround is a major improvement, and the best we have, so I'll add it to my OLPC derivative of the Ubuntu sugar-write-activity package. http://dev.laptop.org/~quozl/y/1bkIWb.txt

add to grub, radeon.dpm=1, according to this link

https://help.ubuntu.com/community/RadeonDriver#Testing_the_driver
makes flickering slower but it does not stop.
GLX version 1.4 and AMD RV710

I changed grub as xorg used high cpu, when opening abi documents.

I'm reopening the Abiword task since there is apparently a flickering problem with abiword on Ubuntu 17.04 Alpha (using GTK 3.22) and one of the developers pointed back to this bug.

http://bugzilla.abisource.com/show_bug.cgi?id=13815#c24

I am running Ubuntu Zesty 17.04 and have this flickering issue. The above fix of changing the theme does nothing to correct the issue. I was using 16.10 prior and did not have this problem. Only after the upgrade did this start to happen. Is there any update on a possible fix for this?

G'day Brian! Yes, the theme workaround began not working for me with 17.04. Yes, the problem can come and go with any changes to the hardware, kernel, X server, or libraries. There is a fix that makes the situation a lot better, see my post last week on the upstream bug https://bugzilla.abisource.com/show_bug.cgi?id=13791#c46 (attachment 5839).

thank you James. I will have a look.

@James- I am sorry, but could you provide a bit of direction on applying that fix? I understand the + and - aspect, but unsure of where/how to apply that. My install was just done through package manager, I wonder if this fix needs to be compiled in?

G'day Brian. Yes, it needs to be compiled in. Download the Ubuntu source package, apply the patch, build the package, then install it. If you've not done that before, you may find it quite complicated. You might enable deb-src entries in your /etc/apt/sources.list file, then "apt-get update", then "apt-get source abiword", then apply the patch, then install build dependencies with "apt-get build-dep abiword", then build with "dpkg-buildpackage", then install with "dpkg -i". There are different ways to do all this, but that's the simplest I can think of. Sorry, I didn't keep the result.

@James- Thanks, I can do the compile and build easy enough. Only question I have then is for the patch, is there an automated way to apply it to the file? I do not have experience in applying changes in this manner, but I can always just change the code. Just hoping to learn more here so I can participate better in the future.

G'day Brian. The patch command automatically applies a patch to a set of files. The particular patch has a sacrificial path element so the --strip 1 option should be used. The --dry-run option is also useful for testing. So it would be "patch --strip 1 --dry-run < file.patch", where file.patch is what was downloaded from the upstream bug report. If that works, repeat again without the --dry-run.

@James- Thanks for all the help. I went through the steps and in the end, nothing was any different. I was at least able to learn some of the steps used here which I really appreciate. I did not see anything too unusual... there was an error on not being able to sign in the end and many warnings throughout (ex. depreciated items, defined but not used variables, etc), but the build did finish and I was able to verify that the patch applied to the proper file. My guess is either something was not right or my experience is just too limited resulting in user error somewhere.

Let me know if and when there are any other options. Thanks again, I really do appreciate what I have learned in the process with your direction.

G'day Brian. Good to hear. For local testing, the signing can be
ignored; there's an option to skip it. The warnings sound familiar,
but are normal. For me, the patch did fix the flickering of the whole
screen, but did not fix the flickering cursor. Guess next steps
upstream involve reproducing and debugging in depth to find out why
the flickering happens.

I have experienced that Abiword cannot be used on plain Debian Stretch, Lubuntu 17.04 and Xubuntu 17.04, all using gtk-3.22. Heavy flickering or moving of paper borders occurs, which stops, together with disappearing cursor, after about 8 seconds without activity. Changing the theme does not have any effect.

Maybe I did not mess it up then. I would agree that the warnings I saw were all non-critical, and it did complete. I am using MATE 17.04 64 bit., gtk 3.22 and is about exactly as Henk explains above. I can also confirm that changing the theme makes no difference for me, and I believe now that the patch is not effective either. I was using 16.10 prior to the upgrade and all worked fine.

I experienced this bug in Lubuntu 16.04, and found it made Abiword unusable. I recently installed Lubuntu 17.04 on a different computer and was disappointed to discover the bug is still present with my fresh installation!

That said, I'm not 100% sure my bug is the same as what is reported here. Above, and at the following places, is described the whole screen flickering when document not empty
- https://www.youtube.com/watch?v=r1lPas9-DuQ&feature=youtu.be
- https://bugzilla.abisource.com/show_bug.cgi?id=13791
- https://bugs.sugarlabs.org/ticket/4915

However, my experience is that Abiword flashes from the top edge of the background (below the ruler) to about an inch into the page on the top, and from the left edge of the background to an eigth of an inch into the page on the left. When I zoom in or out on the document, the same area of the screen flickers. This happens even on an empty document.

I think this is the same problem
- https://askubuntu.com/questions/818219/abiword-documents-borders-keeps-flashing

I tried this:
  for i in `ls /usr/share/themes`; do echo $i; GTK_THEME="$i" abiword; done
It was the same for every theme, including Adwaita.

Any hope for a fix?

Your observation on the visual effects is likely the same as mine which I reported as bug #1649001. However this was considered as a duplicate of #1574278.
Focuswriter or LibreOffice Writer can be installed as suitable alternatives.

Note the flashing/flickering effect in the YouTube video "Lubuntu 17.10 Alpha 2 Stable As Ever" at 3'44".
https://youtu.be/3tKVjBCA_Nw

Confirm the bug with the dafault Xubuntu theme.
$ env GTK_THEME=Abiword
solves the problem, no more flickering

> GTK_THEME=Abiword solves the problem, no more flickering

Does not solve for me on Artful 17.10.

> GTK_THEME=Abiword solves the problem, no more flickering

Also for me it did not solve the problem on Lubuntu Artful 17.10.

Used the same test that Sondra on #43 and also with no luck on any theme

Lubuntu 17.04

Thanks for the bump, I'd forgotten to update this bug.

I found the cause of the problem and fixed it for systems using Xorg. It was a race condition, and is affected by speed of computer, speed of graphics, other processes, and theme drawing. That's why it may not happen for some people. You can find my patch in the upstream bug report https://bugzilla.abisource.com/show_bug.cgi?id=13791 and my summary at Sugar Labs https://bugs.sugarlabs.org/ticket/4915

I'll be shipping the fix on the laptops we make at One Laptop per Child.

However, my fix was not tested on Wayland and caused AbiWord to fail differently under Wayland, and upstream (correctly) refused to accept the patch as is, and nobody seems to have done anything since.

I'm not using Wayland, and I'm not paid to support Wayland, so I'm unable to easily work further on the problem.

But if any of you really need it to work using Xorg (e.g. Lubuntu), my patch should be fine, and I'm happy to explain what the problem was in detail.

Upstream would obviously benefit from someone who can program C++ with GTK+ on both Xorg and Wayland. If this is you, please offer to help them. It has been almost two years since this problem first began, and it is slowly but surely destroying the usability of AbiWord. Sad to see the old girl go.

Since Wayland is not supported by Lubuntu, the only flavor that ships it by default, and stock Ubuntu has their own replacement, I'm willing to have this fix in Ubuntu.

I uploaded a fix to ppa:tsimonq2/universe-upload-testing. It would be great if someone could test it and if it works, I'll upload it.

Here's the diff: https://launchpadlibrarian.net/338474460/abiword_3.0.2-3_3.0.2-3ubuntu1~ppa1.diff.gz

Thanks. Reviewed abiword_3.0.2-3_3.0.2-3ubuntu1~ppa1.diff.gz ... looks right to me.

Ok, did you get a chance to test it or did you just review the diff?

Sorry Simon, I had already tested my patch with my own local package, I didn't think you'd need me to test your package of it, and I'm hoping to hear if anybody else has tested it. ;-)

On a 17.10 Artful VM with Sugar, the Sugar desktop does not appear, some other problem, so I'm not able to test there yet.

On a 17.04 Zesty VM with Sugar, installed your libabiword-3.0_3.0.2-3ubuntu1~ppa1_amd64.deb and the flickering problem has gone. So your package works for me there.

Any chance of a 16.04 Xenial update? A "gir1.2-abi-3.0 breaks gir1.2-abiword-3.0" problem occurs, easily explained.

Uploaded to Artful, I can confirm it fixes the problem. I'll upload packages to test this in my PPA before Monday.

This bug was fixed in the package abiword - 3.0.2-3ubuntu1

Thanks for squashing this bug :-)

Also I can confirm this annoying flashing has gone on Lubuntu 17.10.
Great!

Hi, any chance to see this patch applied on Zeisty?

Thanks in advance

Ubuntu 17.04 "Zesty" will be End of Life this week. Please upgrade to Ubuntu 17.10 or stick with LTS releases if you don't want to be forced to upgrade regularly.

https://wiki.ubuntu.com/Releases

Any chance of a fix in Ubuntu 16.04 LTS Xenial?

As a derivative, I'm carrying a custom package, which is fine
technically, but is hard to explain.

Ubuntu 18.04 beta is unaffected.

Sorry for the delay, I'm working on getting this in Xenial now.

Thanks.

So after attempting to apply this patch, it seems like the code here is totally different.

James, do you have a patch that can cleanly apply to the abiword in Xenial?

For now, I'll reassign this to you. If you aren't willing to do this, that's perfectly fine, just unassign it. :)

If you get a fix that cleanly applies to Xenial, you can reassign to me.

Thanks!

Thanks for the offer. Sorry, I don't have a backport of my patch for
abiword 3.0.1, and haven't estimated the effort. Would you consider
moving Xenial to abiword 3.0.2?

At One Laptop per Child for our derivative build of Ubuntu with the
Sugar desktop, we've worked around the flickering by setting
GTK_THEME to adwaita in the package sugar-write-activity. This
perturbs the timing just enough to prevent the problem on our
supported hardware.

For our upcoming Bionic build, the abiword 3.0.2-6 package doesn't
show the problem.

Hi everyone,
I've just commited a fix for this and other flickering bugs. Please abiword
from shn head and let me know how it works. I apologize for taking so long
to fix this, cheers
