Bug ID: 494451
Summary: Desktop session freezes for several minutes after

desktop session was locked
Classification: Plasma
Product: plasmashell
Version: 6.1.5
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR

syscall trace of kwin_wayland while the desktop was frozen.
SUMMARY
STEPS TO REPRODUCE
1. Lock desktop
2. Receive notifications in Google Chrome (I don't know if this is a
requirement, perhaps any desktop notification will do)
3. Unlock desktop
OBSERVED RESULT
Desktop freezes for several minutes after unlocking, followed by many crash
handler dialog boxes which contain no useful information. The freeze is
observed only if notifications are received while the desktop is locked.
EXPECTED RESULT
After unlocking, the desktop session should be usable immediately.

ADDITIONAL INFORMATION
I ran strace on the kwin_wayland process and it had some interesting busy loop
behavior where getpid() was called repeatedly. I've attached the trace to this
bug report.
Perhaps this is important?
