SUMMARY
On Plasma Wayland, when I resume from sleep mode, I get no output on my monitor and the only way to workaround the problem is to kill kwin or restart the computer.

STEPS TO REPRODUCE
1. Use Plasma Wayland
2. Put system into sleep mode, not hibernate
3. Resume from sleep mode
4. No output is shown

OBSERVED RESULT
When resuming from sleep, I have nothing on my screen and my monitor says their is no output 

EXPECTED RESULT
The lock screen should show up like normal when resuming from sleep mode

It would be good to know what config KWin is failing to apply. Please add
> QT_LOGGING_RULES="kwin_*.debug=true"
to /etc/environment, reboot, make the bug happen again and upload the log again.
A dmesg output with drm debug logging enabled (https://invent.kde.org/plasma/kwin/-/wikis/Debugging-DRM-issues) would be very helpful as well

It appears that on the upcoming Kubuntu 23.04, the issue seems to be fixed. I tested using the daily images of Lunar Lobster. This suggests that it is either an old kernel causing the issue or a distro issue that has been fixed.
