Description Toby 2024-08-20 11:53:53 UTC
SUMMARY
When hovering over task icons, clicking on task icons, previewing app thumbnail, transitioning from hover to bottom align (resulting from maximise window), the entire plasmashell crashes at a high rate. By high rate I mean perhaps one in 10 or 20 events. Typically, once hovering over a task icon causes crashing, it will continue to cause crashing over and over after plasma auto restart.

STEPS TO REPRODUCE
1.  Start a few applications, Firefox, RDC in my case
2.  Hover over the icons, click on the icons, preview content

OBSERVED RESULT
Plasma shell will freeze and crash and automatically restart

EXPECTED RESULT
To be able to switch between applications, preview window content etc

Cannot reproduce with current git master, at least on Wayland.

If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the `coredumpctl` command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl?

Thanks!
