Bug ID: 362955
Summary: (Auto)Suspending compositing sometimes results in
stale non-composited picture
Product: kwin
Version: 5.6.4
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: compositing

Support information while the issue is NOT present.
Not sure if it's a bug in kwin or plasmashell. I have a kwin rule to disable
compositing once mpv launches. Sometimes, this results in plasmashell
displaying a stale image - this affects the whole UI. For example, the
icon-only task manager shows applications that were running the last time
compositing was activated. Starting new applications does neither display the
loading circle animation, nor show the application icon once the application
starts.
The more annoying part about it is that the clock and the widgets are showing
stale information, too. I once nearly missed and appointment because both
clocks were still saying it's 16:30 while it was starting to get dark...
I have also remember being able to trigger it by manually suspending
compositing, but that might have been after it was already bugged by launching
mpv.
Arch linux x64, fully updated as of yesterday, nvidia 340xx blob (260GTX). Has
been happening since forever, but that's not surprising since I'm on the legacy
branch.
