Using HP Reverb G2 with NVidia 2080S, latest drivers for everything. If Windows HD Colour settings has “Use HDR” enabled (I have an HDR monitor) then when in VR mode Flight Simulator shows a pure yellow display and no content through the headset. All other VR applications seem to work OK with HDR mode enabled. Using Windows Mixed Reality, not SteamVR. There are other reports of this on Reddit and elsewhere, so seems to be a general issue (not specific to the 2080S).
Thank you Noted.
