Created attachment 126319 [details] crash plasma desktop See my attached for more info about the crash.
This bug happens with many scenarios and sometimes no bug report is detected in notification area, here is a stack-trace from another scenario different from the one in the attached video but it leads to the same crash Application: Plasma (plasmashell), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
