Bug ID: 434385
Summary: Taskbar freezes regularly when Compositor is set to
XRender
Product: plasmashell
Version: 5.21.1
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: e...@hotmail.de
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
When the compositor is set to XRender, the taskbar freezes regularly and the
system becomes unusable because of that. I have to reboot or restart the
plasmashell to get it back working.
The bug occurs after some time of usage. Sometimes after a couple of minutes,
sometimes after a few hours. But it occurs multiple times a day and made me
switch to Gnome for a while (I had this bug for at least year). While searching
in forums, I found quite a number of people having a freezing taskbar problem.
Only recently I noticed that this is dependent on the compositor backend.
There is another bug report which mentions the compositor backends, but for me
it's exactly the other way around as in Bug 425557. Both OpenGL backends do not
seem to trigger the bug on my system (ThinkPad with Intel Graphics)
I need to use XRender though because of another bug. Screencasts or
TeamViewer/Anydesk sessions with the OpenGL backends result in flickering,
where the desktop background behind a window appears in some frames.
STEPS TO REPRODUCE
1. Just run plasma with XRender backend and work till the taskbar freezes
OBSERVED RESULT
The taskbar freezes completely and cannot be unfrozen. I need to restart the
plasmashell.
EXPECTED RESULT
Not freezing ;-)
