eziowar

Hi, my os- win11,  gpu - Asrock AMD rx 7800xt challenger oc, Monitor- acer nitro vg271u m3

I enabled HDR in windows 11, in game and in monitor's OSD settings.  this issue happening each game which supports HDR natively (not auto hdr). The issue is- during fullscreen gaming whenever i alt tab and focus to other apps instead the game window or if i run the game in windowed mode , the in game colors gets more vibrant (guessing this is  actually HDR getting disabled) but when i just run the game fullscreen the colors gets less vibrant (guessing this is  actually HDR getting disabled?). 

Showing a video of this, u can see when i alt tab the game goes more vibrant - [MEDIA=imgur]abJQZ4D[/MEDIA]

I'm providing Dxdiag result for display - and screenshot from windows settings -> system -> display -> advanced display
