Bug ID: 517278
Summary: Kwin randomly resets graphics every once in a while
Classification: Plasma
Product: kwin
Version First 6.6.1
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
When running Plasma, Kwin will randomly will reset graphics, and occasionally
freeze during use (requiring a forced shutdown). For context, I am on a laptop
with Intel Iris Xe graphics, using the experimental Xe driver (however, I've
noticed this issue happening much more frequently in recent versions of
Plasma). This happens usually when doing anything with an app, or when
interacting with the desktop in any way.
STEPS TO REPRODUCE
Currently unable to figure out how to reproduce the issue, it seems to happen
on a random.
OBSERVED RESULT
Graphics resets and, occasionally, the screen will freeze, requiring a forced
shutdown.
EXPECTED RESULT
No random resets or freezes.

ADDITIONAL INFORMATION
Checking journalctl, this is what I find around the point of the most reset
graphics reset (this time after opening Discover):
