Bug ID: 491699
Summary: Occasional crash when clicking on task manager icons
Classification: Plasma
Product: plasmashell
Version: 6.1.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Task Manager and Icons-Only Task Manager
Assignee: plasma-b...@kde.org
Reporter: adam.m.fontenot+...@gmail.com

Target Milestone: 1.0

kcrash info
Every now and then, with no obvious cause, clicking on an icon in the
Icons-Only Task Manager will crash plasmashell. When this happens it instantly
restarts (my Plasma session is systemd), and if I click on an icon again I will
immediately get another crash. I can easily crash plasmashell over and over
many times this way.
Eventually (after a minute or two?) the problem goes away, and the reason this
happens is equally unclear.
Switching windows via any other method does not cause a crash - *including*
hovering over the task manager so that the preview widget appears and clicking
one of the previews.
I do have a multi-monitor setup, though that isn't related in any obvious way -
it doesn't happen consistently when I switch monitors, and there's no visual
glitch or any other indication this is related. I mention it only because it is
unfortunately related to the Plasma crashes I see more often than not.
