New crash information added by DrKonqi
plasmashell (5.18.5) using Qt 5.14.2
- What I was doing when the application crashed:
It usually happens when I am doing actions which involve the workspace or managing windows.
- Unusual behavior I noticed:
plasmashell gets killed, then either the screen goes black and then returns with plasmashell restarted or if it cant be restarted I have to access the Desktop by Krunner
- Custom settings of the application:
Aritim-Dark global theme
Arc-Dark Plasma style
Materia Manjaro Dark Solid window decoration
Breeze GTK-2 application style
Dark-Oympic GTK-3 application style

I found out that it only happens when I use an external display on the internal graphic port of the Thinkpad T470p. When I don't use an external display, this bug doesn't occur. The same thing when I'm using the ports of the docking station. Is this still a problem for you with Plasma 5.27?
The only interesting thing I saw in the backtrace was this:

Created attachment 129980 [details] Debug log of plasmashell SUMMARY After a certain amount of time plasmashell seems to hang for unknown reasons. This means that no interaction with the panels is possible anymore and the desktop doesn't update (only the windows rendered above are visible). Certain features of the desktop are functional when the hang occurs. This includes the task switcher and global shortcuts like for invoking krunner or the task manager. But sometimes, krunner is affected as well. Sometimes it seem to affect the stability of unrelated applications (Chromium browser, Elektron Apps) as well. This behavior is present at least since March 2020. STEPS TO REPRODUCE Sadly I don't know how I can reproduce this behavior. But it seems to be related with some kind of user activity. It's also my work system so I don't want to tinker too much. I tried my best to give you as much information as possible. SOFTWARE/OS VERSIONS Linux/KDE Plasma: NixOS 5.4.50 20.09pre233323.dc80d7bc4a2 64 bit (available in About System) KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.7 The hardware is a Thinkpad T470p with Intel graphics. There's always plenty of RAM and CPU available. I'm always using one or two external displays. ADDITIONAL INFORMATION Once I kill/restart the plasmashell process, everything is functional again. I tried to turn on some logging but there are no traces of an error for me. I attached the output of the following command line until the hang behavior occurs: env QT_LOGGING_RULES="* = true; qt.scenegraph.* = false; qt.quick.hover.trace = false; qt.qpa.events = false; qt.qpa.input.* = false; qt.quick.mouse.target = false;" plasmashell --replace 2>&1 | gawk '{ print strftime("[ %T ]%t") $0 }' > plasma_report.log I filtered some very noisy events since they seemed to be rather unrelated.
