A few updates ago I noticed that plasmashell has regularly been using about 40-78% CPU and some extra RAM on a regular basis this never happened, is something wrong?
I have also noticed that the plasmashell process constantly eats about 70%-80% CPU time.
Digging into it I found out I have a widget (zren’s command prompt) with an runtime interval of 0 that was executing a command in a busy loop. Putting a reasonable interval on that execution dropped the CPU usage to virtually 0%.
Check - you might have a runaway widget on your hand.
this also seems to be a new behavior, perhaps someone who works on plasmashell could help us?
turns out having 2 widgets with 1 hour of history each uses a some CPU
