Kwin tint
External monitor (HDMI) shows pink color tint after resuming from suspend.
Unplugging/replugging the cable does not fix it. Forcing RGB range to Full does
not fix it. Forcing max bpc to 8 does not fix it. Logging out and back in
mostly fixes it, but reboot always fixes it.
Journal shows repeated "kwin_wayland_drm: Atomic modeset test failed! Invalid
argument" errors around the time the tint occurs, across multiple separate
days. The errors stop after the KWin process is restarted (logout/login).
To reproduce connect external monitor via HDMI, use normally, suspend (lid
close or manual suspend) and
resume, but is does not reproduce it consistently.
Night Color set to allways off.
External monitor colors are pink/magenta-tinted after resume. Internal display
unaffected. Persists until logout/login or reboot.
