SUMMARY

I'm experiencing an issue for about half a year now. When I leave my machine with the screen locked and log back in afterwards, I see dozens of messages that kwin had crashed.

***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. lock screen
2. leave machine for some time
3. log back in

OBSERVED RESULT
kwin has crashed; restarting plasmashell solves it.

EXPECTED RESULT
Everything would continue working.
