Windows 11 is changing my screen brightness while I am actively using Apps

Could you confirm if HDR is enabled on your system? If not, To enable HDR and Auto HDR in Windows 11, please follow these steps:

1. Enable HDR in Windows 11:
   
   • Navigate to Settings > System > Display.
     
   • Toggle on "Use HDR" under the "HDR" section.
     
2. Enable Auto HDR:
   
   • Within the same Display settings, toggle on "Use Auto HDR".
     

Once HDR and Auto HDR are enabled, you'll notice the "SDR content brightness" slider under the HDR settings. Now, proceed to adjust the SDR content brightness slider:

1. Adjust the SDR Content Brightness Slider:
   
   • The SDR content brightness slider regulates the brightness of non-HDR content, such as the desktop and file explorer, when HDR is enabled. This adjustment may potentially resolve the issue you're facing.
     

If the issue persists after these adjustments, you may consider the following troubleshooting steps:

• Connect a different monitor to your PC to determine if the issue lies with your monitor or your PC.
  
• Alternatively, if you're experiencing significant difficulties, reverting to Windows 10 could be an option to explore.
  

Please let me know if you require any further assistance or clarification.

HDR fullscreen problems

Version: Windows 10 17134

GPU: NVIDIA 1080 Ti (Driver 397.31)

Display: LG OLED 55" B6P

Problem: Windows HDR implementation barely works properly. Here's a list of issues I've seen so far:

1: SDR applications that are not exclusive fullscreen start in HDR mode, distorting the colors. If an OS overlay [such as the volume overlay] come up, the display will go blank until the overlay dissapears.

2: SDR applications that are exclusive fullscreen go blank. From what I can see, my display is in SDR mode, so I'm guessing there's a mismatch between Windows trying to output HDR content and the display receiving it. [And no, the problem is on Windows
end; the display can handle HDR just fine on other systems]

3: I've had a case where an SDR application, on exit, somehow resulted in the system HDR setting being disabled. I've also had another case where on exit the system is reporting its in HDR mode, but outputting SDR even on the desktop.

So in short: Windows is not managing HDR properly.
