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.
