I see the exact same issue reported but by someone who has Crossfire enabled. ( Full Screen games Flickering )
I do not.
This is my system :
Motherboard : Asus Z97-K
CPU: Intel 4690K
Ram: 32 GB Kingston 1866
Video: Sapphire R9 280X Toxic
After i installed the new driver i can not play any game in full screen.
Games tried : NFS Rivals
What happens is that the game starts and it starts flickering on my screen , then just a blank screen. If i alt tab it and then go back to the game , but in Window game it works , BUT i want to play my games fullscreen.
In my opinion this is TOO MUCH. You can't release a driver that behaves like that. You just can not. Please fix it ASAP .
