SUMMARY
Under wayland, login works fine but when the monitor goes to sleep it wakes up
to a blank screen.
Under X11, login immediately produces the blank screen.
Both kwin and plasmashell say up and running.
STEPS TO REPRODUCE
1. Let system idle until monitor falls asleep
2. Move mouse
3.
OBSERVED RESULT
Blank white/light gray screen with cursor still responsive. As in cursor moves
and changes form based on what hidden window is underneath.
EXPECTED RESULT
Desktop and windows visible.

ADDITIONAL INFORMATION
This is a new system using AMD integrated graphics (RDNA 2) and a single
monitor plugged in with HDMI. I disabled screen locking and it still occurs. I
tried creating a new user with fresh config. I can switch to another virtual
console. On X11 when I switch back I briefly see the desktop. This issue was
also recently reported in
https://forums.gentoo.org/viewtopic-p-8768658.html?sid=6f7dccffd7790600c6e13d6afcae57d2.
Unfortunately that user gave up and moved to xmonad. I now have
export QT_LOGGING_RULES="kwin_*.debug=true"
in .bash_profile, and have looked through the journal but not sure what to look
for.
