Lines aren't rendered with default background color after end of content

[th0br0]

Description

Lines aren't filled with default line background color after the end of the line content. This was observed on pre-emacs-25 as well. Only manoj-dark and wheatgrass don't seem to have this issue. Background color differs between light/dark themes: either a bright or dark blue color.

Reproduction guide

This may be directly related to Emacs (or GTK). I'm getting the same issue even if I run emacs -Q and manually set the background to red the frame background turns black. If i set it to white, the frame becomes blue

@korayal what version of Emacs are you using?

[th0br0]

As far as I know, that's highly likely (or at least it's one of the reasons). There's an open upstream ticket at https://debbugs.gnu.org/cgi/bugreport.cgi?bug=20882

@korayal do you happen to be using xmonad?

[korayal]

@d12frosted I'm using emacs-24.5.1 but I also tried out emacs-snapshot package in ubuntu xenial and the issue is still there.

@th0br0 I'm on gnome 3.19.90 but I had the same issue on xmonad too.

UPDATE: I installed emacs24-lucid instead of emacs24 and it started working alright. I think this issue is about GTK

[danielrenninghoff]

I also ran into this issue yesterday on Fedora 24. Todays update to gtk3-3.20.2 has fixed the issue though, so this doesn't seem to be an emacs or a spacemacs bug.

@th0br0 Can you also try if updating gtk fixes your issue?

[korayal]

I switched back to emacs24 again and it seems the gtk update did the trick.

[Aletheia-Lothlorien]

Had the same issue with OpenSuse Tumbleweed. Upgraded gtk today and now back to normal.

Closing as this issue is fixed upstream.
