Summary: plasmashell sometimes crashes when the list of task
manager windows changes
Classification: Plasma
Product: plasmashell

Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: k...@ashka.me
Target Milestone: 1.0
Application: plasmashell (6.1.4)
Qt Version: 6.7.2
Frameworks Version: 6.4.0
Operating System: Linux 6.10.3-arch1-2 x86_64
Windowing System: Wayland

-- Information about the crash:
When a new window is created, an existing window is closed, an existing window
is highlighted, or a popup is created (so not listed in the task manager),
plasmashell seems to crash at random. This used to happen in 6.1.1 and happens
in 6.1.4. I do not remember having it happen in 6.0.5 that I was using before.
On regular use, this seems to happen 5-10 times a day.
I have 2 screens and one of them is scaled at 200%, I feel like it did not
happen when I had a single screen.
The crash can be reproduced sometimes.
