When I set the refresh rate of my asus vg248qe to 144hz, the screen randomly flickers several times per minute on the desktop and sometimes happens when gaming. It doesn't happen on any refresh rate below 144hz, such as 120hz, 80hz, 60hz etc.

I've tested this monitor on my gtx 970 and r9 290 and the problem only occurs on my new rx 480. When using the rx 480 without its drivers this issue does not occur, however..
