Some games do not start when HDR is enabled

[0x4d4d]

The following games do not start when HDR is enabled:

• Tomb Raider
• Ori and the Blind Forest: Definitive Edition
• Red Wings: Aces of the Sky
• ... and some other games too

Ori and Red Wings fail to start with an error window containing these lines:

Switching to resolution 3840x2160 failed, trying lower one
Switching to resolution 3840x2160 failed, trying lower one
All resolution switches have failed
Screen: DX11 could not switch resolution (3840x2160 fs=1 hz=0)

When I try to start Tomb Raider, a black screen appears briefly, and then the steam big picture is displayed again.

For all games it helps to disable HDR and after the game lunched its not a problem to enable HDR again.

Some logs of starting red wings when HDR is enabled and disabled:
redwings-hdr-on.log
redwings-hdr-off.log

I found this discussion on the Steam forum with the same error message.

How did you disabled HDR ?
I've set "mat_hdr_level 0" as launch option on games that have the exact same issue you encounter on Ori and Red Wings but it didn't solve the issue for me. How did you disabled HDR for those games ?

The only fix I've found is to launch in desktop mode which isn't ideal as I use ChimeraOS to avoid Desktop mode in my living room

My workaround in GamingMode is to disable HDR globally before starting via Settings -> Display or Quick Access Menu and enable it again for games that support HDR.
