Description derplip 2021-11-11 12:09:02 UTC

I have the problem that the control panel regularly disappears. Sometimes it comes back on its own, sometimes I have to restart the Plasmashell process via console. In the first case, I occasionally (not always) see the icon for a crash report. However, it tells me that it is probably unusable because some debug libraries are missing. I gave up trying to install them because I couldn't find most of them in the Debian repo.


STEPS TO REPRODUCE
The problem usually occurs after changing the monitor setup, I often switch between different docking stations. However, it doesn't happen right after the change, but mostly after I've been working for a while. 

OBSERVED RESULT
Plasmahell crashes

EXPECTED RESULT
Plasmahell does not crash
