I had the same issue(SD oled user here) and i found a fix but cant find the link for some reason. So what I did was when you load the game, press the quick access settings(right steam button) and leave it on, if it goes away keep pressing it until you pass the white screen, then go to settings and turn Vsync off. You shouldnt have any issues when you restart the game.

I have rog ally and switch oled and thinking getting the GO soon. But bc im impulsive, pulled the trigger on SD 512 oled. It will be my very first SD so i hope i like it.
