Bug ID: 511059
Summary: kwin crashes when waking up monitors from standby
Classification: Plasma
Product: kwin
Version First 6.5.0
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: generic-crash
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
kwin crashes when waking up monitors from standby.
STEPS TO REPRODUCE
Lock with win+L, press escape to put monitors in standby. It seems that waking
up the monitors immediately doesn't cause the crash to happen. It may be needed
to wait for a long time (hour+). Happened twice.
