Without GE proton, I launch this game, then as you can see in this recording the screen is totally black but it has actual game audio runs in the background. I tried with GE proton, 8-25,24,23, and experimental version, but none of them works, they all have the same problem. I also tried reboot SD, still doesn’t work.

I know this game is running in the background but the screen just shows nothing. When I switch to the desktop model, I can play horizon 4 without any problem. I believe it should be some software problem with the oled version. Becasue I also have a lcd SD with the same latest Steam OS 3.5.7 and the lcd SD has no problem when playing horizon 4.

Hope anyone can help me on this issue. Thanks.
