Unable to get a snap of it when it happens, but sometimes when I move my mouse at all or move the camera in the game, it is almost as if the screen is made up of segmented blocks. You can see lines that run about 1/8 to 1/4 the screen length in a horizontal manner, almost as if someone badly stitched images together in photoshop to form one large picture.
Running an i5, 12gb sniper ram, r9 290x rig with witcher 3 on high. On 4k res, these lines are worse than with 1900x.
