SUMMARY
I have Benq Ex240 monitor. Arch linux. Nvidia 2080ti with Wayland. Using a
DisplayPort cable.
When "adaptive sync" is set to Automatic or On in KDE Display settings, then
turning off and on monitor , the VRR functionality is broken and when
fullscreening apps / youtube videos, the screen flickers black periodically or
for very long periods of time. If I go into Monitor menu, it says VRR is off,
but its like Wayland is trying to force it on?
STEPS TO REPRODUCE
1. Turn on Adaptive sync automatic / on
2. Turn off monitor, turn back on
3. Fullscreen a youtube video, application, game, etc
OBSERVED RESULT
Screen flickers black or stays black for long periods of time. Monitor OSD says
VRR off.
It can be fixed to work properly again by either quickly switching resolution
back and forth, or switching refresh rate back and forth after turning monitor
on again.
EXPECTED RESULT
VRR works fine before turning off monitor, no flickering, or black screen.
Should be same after turning back on.
