Separator lines in shell popup menus are too faint to see

Those lines aren't blank. They're horizontal separators. Unfortunately those horizontal separator lines are so faint you can hardly notice them. Maybe on some monitors they're not visible at all. I can see them but honestly didn't notice they existed until today!

So I think the colours in our theme for separator lines might need improving, but that's a minor theme issue.

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

Verified this bug is fixed in bionic version 3.28.3-0ubuntu0.18.04.3, but it introduces a rather bad regression where the login screen is now the upstream grey theme.

OK, I wiped another laptop and installed 18.04.1 fresh with only the above fix.

Verified bug fixed with no regressions, using 3.28.3-0ubuntu0.18.04.3.

This bug was fixed in the package gnome-shell - 3.28.3-0ubuntu0.18.04.3
