Forgot to add, #6 is about this scenario https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1722000 from a duplicated bug.

I can now change scaling to 200% on an external monitor and gnome shell doesn't crash.

Can you still reproduce this in 3.26.1-0ubuntu3 and onwards?

Could you check if the patch attached to https://bugzilla.gnome.org/show_bug.cgi?id=789070 fixes the issue?

It looks like a workaround to me, but still
