Bug ID: 462063
Summary: Task manager flickers
Classification: Plasma
Product: kwin
Version: 5.25.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: ptsel...@outlook.com
Target Milestone: ---
SUMMARY
***
I have to admit that I haven't pin-point the root cause of this.
It happens completely randomly but it's quite often. The only solution I have
found so far is to restart the PC.
***
What is happening:
Icons in the task manager flicker between the active and the previously active
window.
It starts randomly. I thought it was caused by Chrome, but then I realized that
is happening with Firefox as well. Also, some times it stops, when I select an
application (either via the Alt-Tab, or via the Task Manager).
I am suspecting a few things but I would prefer to explorer some options as
well as a strategy to identify the possible root cause with someone what knows
better the underline technology.
STEPS TO REPRODUCE
1. No idea. I have no idea how it started or how to re-produce it, or why it
stops or how it stops!
OBSERVED RESULT
Please check this short video: https://vimeo.com/manage/videos/773024690
