Bug ID: 448062
Summary: Crash in operator()<KWin::DrmObject*>
Product: kwin
Version: 5.23.4
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: platform-drm
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
KWin suddenly crashed. I obtained the provided backtrace.
STEPS TO REPRODUCE
1. I was using the computer normally. Multiple windows were open, and I was
moving the mouse around. I do not remember anything particularly special.
2. Maybe it is relevant that a system upgrade was running in a background
terminal, but at least the main part of the upgrade was already finished when
the crash happened judging by the logs.
3. I was unable to reproduce the crash.
OBSERVED RESULT
KWin crashed.
EXPECTED RESULT
KWin keeps running.
