Bug ID: 511880
Summary: Kwin-wayland randomly crashes
Classification: Plasma
Product: kwin
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Kwin-wayland randomly crashes.
STEPS TO REPRODUCE
I cannot reliably reproduce the issue. The crash happens about once in a day or
two. It usually happens when I open some program (often, but not limited to,
Firefox), but it happened also when switching focus to another program. I could
not find any reliable pattern.
OBSERVED RESULT
The screen goes black for a while, then everything returns. If Firefox was
running, it crashes and instead of it I see only crash reporting dialog.
Controlling screen backlight does not work until system restart. Other programs
seem to be unaffected.
EXPECTED RESULT
Not crashing.
