-- Information about the crash:
I hear constant 'bell' type notifications whenever screens are turned off, either 'naturally' i.e. display off timeout expires after screenlocks after inactivity timeout,  or if I manualll lock with meta-L then turn displays off with 'Esc' key. After a while powerdevil, I think or maybe plasmashell ?!?. crashes.

If I leave my PC for a while like this it becomes sluggish when I unlock. If I leave it long enough it is down-right unresponsive to the point I choose or have to reboot to restore usabilty, sometimes forceably using 'magic' sysreq

Has been a problem since Plasma 6.something, but wasn't happening with Plasma 5.

I have a 3 monitor setup.

The crash can be reproduced every time.
