Every time I Alt+Tab out of a game in exclusive fullscreen and back in again, my screen starts turning off and on again, i.e. flashes in 1 second intervals. Makes the whole thing unresponsive for 15 seconds to a minute. Borderless Window works just fine, but this is not an option with every game. This is really annoying as it did not happen with my previous (nvidia) card, so I doubt the problem is related to Windows 10. Any hints would be appreciated, this problem exists since I got the AMD card.
