Hello there,
So I'm currently using an Sapphire r9 fury tri-x, with the 18.1.1 drivers (+ ryzen 5 1600 @3.8GHz), and since the 17.12.1 drivers I'm experiencing random blackscreens with the game still running in the background (observed in CS:GO and Rainbow six siege).
Radeon Chill is enabled (between 60 and 75 FPS) and I'm using a freesync display, so I guess it has something to do with drivers.
Thank you for your attention
