R9 280X CF problems when gaming in fullscreen !

[Peterr Peter]

Hi , i am using 2 sapphire r9 280X GPUs . one Dual-x and the other Vapor X . Running AMD driver packaging version 15.30.1025.1001-151204a-296872C . All games run just fine , IF IN WINDOWED MODE ! when i switch to fullscreen mode , the screen starts to flicker in a pinkisk darkish color , while the game screen is still visible , switching back to windowed mode solves the problem .... The gpu-s were used for bitcoin mining for a short period . So if you have any idea what can i do to , please share

Just wondering why did u buy R9 280Xs if you had 7970s they are basically the same card. OC it a little and voila!

iu got them for free .... and sold my 7970s ..... anyway i am wondering if its a hardware issue or a softwave/driver issue .... if i stretch the windowed mode game to almost fullscreen(i just see the bar on the top) its fine .... hit alt+enter , fireworks go off
