Bug ID: 449957
Summary: KWin crash when turning off or unplugging monitor
Product: kwin
Version: 5.24.0
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org

SUMMARY
I have a monitor attached to a port of a Thunderbolt dock via DisplayPort. KWin
crashes whenever I switch off the monitor, or unplug it, or unplug or switch
off the dock it's attached to.
STEPS TO REPRODUCE
1. Switch off the external monitor, or unplug it, or unplug or switch off the
dock it's attached to.
OBSERVED RESULT
KWin crashes, taking down all applications.
In addition, when KWin comes up again right after the crash, I see the Akonadi
crash reported in bug 445249.
EXPECTED RESULT
KWin should survive the disconnection.

ADDITIONAL INFORMATION
The bug has been present for a while, at least since 5.23, so it's not a 5.24
regression. I didn't report it earlier because I mistook it for bug 438839.
