Summary: KWin crashed when dragging file over Task Manager
Product: kwin
Version: 5.13.1
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: kacperkas...@gmail.com
Target Milestone: ---
This was actually a one time crash, that I can't reproduce anymore.
Plasmashell crashed a moment before, there is a separate bug report for that:
