Bug ID: 497440
Summary: Task Manager freezes
Classification: Plasma
Product: plasmashell
Version: 6.2.4
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Task Manager and Icons-Only Task Manager
Assignee: plasma-b...@kde.org
Reporter: andrew.minc...@gmail.com
CC: qydwhotm...@gmail.com
Target Milestone: 1.0
SUMMARY
The Icon-Only Task Manager freezes randomly (clicking on the icons has no
effect).
Killing and restarting the plasma shell solves the problem, but this is a
non-ideal solution.
STEPS TO REPRODUCE
This happens randomly, and I have no idea how to reproduce it.
OBSERVED RESULT
Icon-Only Task Manager freezes -- clicking on the icons has no effect.
EXPECTED RESULT
Clicking on the icons should allow me to switch between apps.
SOFTWARE/OS VERSIONS
OS: openSUSE Tumbleweed 20241210
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.1
ADDITIONAL INFORMATION
I was just browsing the Internet when I noticed the problem. The freeze might
have occurred earlier but I did not notice that.
Following are the logs I got from `journalctl -xe | grep plasmashell`. From the
logs, it seems that the problem might be screen-related? I have two monitors
connected to my desktop. One is a regular monitor and the other is a headless
HDMI monitor (a display emulator). When the freeze happened, I was only using
the regular monitor with the headless one disabled.
