AMD GPU's having extreme brightness increasing in my game

This has been reported by my players using both the RX560 and RX570 GPU's. The brightness keeps increasing once the scene loads until you pretty much can't see anything. It almost looks like exposure in the post processing is being turned up, but I do NOT have it enabled. PP is enabled, but not exposure. Is there a solution to this?

 

I'd ask the users who are reporting this issue to check if they have "Vari-Bright" enabled in the Radeon display settings. It is a feature which automatically changes display brightness and gamma levels to minimize display power usage. Some other settings I'd check would be "Display Color Enhancement", "Radeon Image Sharpening", and maybe a few others. You might also check what driver version they are using.
