Screen flashing in HDR and fullscreen any window
Made short clip demonstrating the problem.
https://youtu.be/dYvNJA1N--Y
I have two screens, one of them is HDR (right) 10bit color and the left one is old ips, no hdr 8bit.
Whenever i have anything, any program, app, game, in full screen or borderless. It will flicker/flash as shown on video when moving cursor to the other screen, or alt tabbing. But it never happens in windowed.
For one of my game, i solved it by making it windowed, while having Titlebar and frame removed, and maximising width and height. So it pretends to be borderless.
But is there any way to fix it other than getting second monitor that also supports HDR?

Yes I have one HDR one not HDR

@Lance put firefox on fullscreen (f11) on the one WITH hdr and move cursor between

My flashing is on mouse input and in the game not in a browser

Have not tried yet in game
After having closed and then opned throne again
flashing is back
I cant do the thing you showed though my mouse is locked to throne
Click drag flash

I wish tho there was some solution in general, to that flashing, HDR related
The only two fixes I have found so far is play in windowed not full screen or disable desktop HDR

HDR with VRR causing Gama/brightness flicker
Mate, many thanks for trying to replicate/test and help out on this! Much appreciated, I own you a beer just for trying. I was actually able to fix this believe it or nor… One of the KDE devs replied to the BUG and pointed it could be a gamescope issue to try to disable HDR in gamescope and run the game. He has right, even if HDR is disab...
