I just bought a nice OLED monitor and I'm trying to take advantage of it to play my games in HDR. If I run my games in gamescope, then HDR runs fine but my PS4 controller doesn't work. If I play without gamescope, the controller works, but HDR does not.

I've been trying to figure this out for a bit, and some people have been having some luck with the -e flag, which does nothing for me.I've tried Steam Input and overlay in all combinations of enabled and disabled and I've tried in big picture/gamepadui. Either way I have to choose between HDR and the controller. Has anyone gotten this to work?
