Hello, opening menus in games and such makes my screen go black for a few seconds and it seems to have to do with when the game has micro stutters. Note this only happens with Freesync enabled, is it the drivers or is the screen faulty? This also happens when a game runs at less than 144hz where my screen constantly goes black for a few seconds at a time.
I'm experiencing that with a few DX11 games but in the opposite - if I go to max 144Hz it randomly goes to a black screen until I exit to the menus, which is consistent with various games (PUBG, Battlefront) and in Ghost Recon Wildlands it starts to flicker but stops. Dropping it to 60Hz clears everything up. I think it's an issue with the drivers in development. I'm currently using 17.9.1 (for RX Vega 64).
