Hello,
I’m running KDE on a computer attached to a TV with HDMI, and I am frequently experiencing KDE having high CPU usage on a single core, forever (until loginctl terminate-user is ran, or the user logs back in) after it disconnects (kwin_wayland and plasmashell) (the cable is not being touched, the TV just seems to do that when powered off for a while). The cooling system is not the strongest so the temperatures get high, which is very annoying. I have also experienced SDDM crashing if no user is logged in and the screen is disconnected - requires a restarting from the TTY or ssh…
I am a bit new to linux and the only interesting output from journalctl /usr/bin/plasmashell i could see is this:
```
Mar 10 18:10:23 ** : requesting unexisting screen available rect -1
Mar 10 18:10:23 ** : There are no outputs - creating placeholder screen
Mar 10 18:10:25 ** : error creating screencast “Could not find window id {***}”
```
