Bug ID: 439681
Summary: kwin_wayland crashed when I repeatedly hovered over
grouped and ungrouped apps in task manager
Product: kwin
Version: git master
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: bugsefor...@gmx.com
Target Milestone: ---
SUMMARY
I had 3 windows of Opera internet browser grouped in task manager, one of them
was playing a video on youtube. I also had a single instance of other apps
(konsole and kinfo center, I guess). I hovered grouped Opera and repeatedly
moved cursor on all apps in task manager. At some point kwin_wayland crashed
and all runnijg apps were aborted.
Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.22.80
KDE Frameworks Version: 5.84.0
