Bug ID: 461156
Summary: kwin locks up with 100% CPU load when external screen
gets plugged in
Classification: Plasma
Product: kwin
Version: 5.26.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Each time I plug in my external screen, kwin just freezes up with 100% CPU
load. I need to SIGKILL it from a tty (SIGTERM is being ignored), and then
somehow get the desktop session to work again.
SOFTWARE/OS VERSIONS
Operating System: Debian GNU/Linux
KDE Plasma Version: 5.26.0
KDE Frameworks Version: 5.98.0
Qt Version: 5.15.6
Kernel Version: 6.0.0-2-amd64 (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Xeon® CPU E3-1505M v5 @ 2.80GHz
Memory: 31,2 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics P530

ADDITIONAL INFORMATION
This is just the last in a series of crash/freeze/hang bugs that kwin_x11 is
suffering from recently. I am not sure if there is something odd about my
system or if nobody is using KDE on X11 any more and hence those codepaths are
just bitrotting.
