I'm having a similar issue. When the display goes to sleep or I turn off the
monitor, some KDE processes (konversation, kmail, akregator, etc) lock up with
100% CPU utilization, and when I wake/turn on the monitor, I just get a blank
screen with a cursor. If I move the cursor, the screen will flicker with dirty
contents and leave mouse trails all over the place. Blindly typing in my
password apparently does nothing. I have found that I can kill the user
(switching to a different tty, e.g. ctrl+alt+f2, kill kwin_wayland and various
other processes running as the user) and it'll bring me back to the login
screen where I can log back in and use the system again. Better than a full
reboot, but hardly makes for a usable system whenever the monitor is turned
off.
I have also found that if I set Adaptive sync to Never in System Settings ->
Display and Monitor, I can turn off the monitor and turn it back on and keep
KWin-Wayland running properly. However the same KDE processes will still lock
up with 100% CPU utilization (they become unresponsive and need to be
closed/restarted), and the Adaptive sync setting resets to Automatic.
Interestingly, this only started when I got a new monitor. I had an old
hand-me-down Samsung monitor connected via HDMI, and never had any issues when
the display went to sleep or I turned off the monitor. But once I replaced it
with a newer LG 27GP850 monitor connected via Display Port, these issues
started.
I'm using Debian Unstable with kde-wayland 5.24.3-1.
