I just bought a new Sapphire Dual-X R9 270 card (Model: 11220-00-20G), and although the card appears to generally be functioning well, I have noticed that black rectangles sometimes appear in the upper right corner of my browser window when some action is taken (i.e. a new tab is opened). The rectangles disappear when I move the mouse pointer over them. I have upgraded to the most recent drivers, but there has been no improvement.
Has anyone had the same problem? Can anyone tell me what's going on and if there's a fix for it? Should there be other issues for which I should check, given that this is going on, and are there any tests that I should run on the card to check for other problems? Thank you.
