Here's a quick video of my issue
Take note around 6 seconds in (sorry for the quality its the only camera I have), the Vibrance/Contrast/Brightness change when the program is engaged. This happens for a large amount of the games that I have, and the Vibrance/Contrast/Brightness will change throughout the game-play randomly. It even happens when I'm not in game. For example ill be playing a game of mw2 and ill Alt-Esc to go browse reddit or something. While the game is running in the background an i'm browsing reddit the Vibrance/Contrast/Brightness will change frequently (1-2 every 5 mins or so) making it annoying to use. But once the program is closed it goes back to being the original Vibrance/Contrast/Brightness. Its not just a gpu issue. I have the same issue with a V5800 and a gtx 750ti on the same ryzen motherboard with the appropriate display drivers. Swaping my 390 over to a I5 board produces no such issue. Ive swapped ram, psu's and PCI-E slots to no avail meaning that most likely its a software issue or an issue with my Ryzen 1700 or B350 Mobo. Switching back to previous graphic's drivers does nothing from what I can tell. All the parts are fully functioning though. Tested with Acer GN246HL and some old Dell 4:3 using multiple different Dvi,HDMI and Display port cables

Thanks for the post, I'm using a Ryzen system and don't see this behaviour.
Is anyone else experiencing a similar issue?
