Graphics card in question: Asus R9280X-DC2T-3GD5-V2 3GB
I have an issue when I move a window (usually a photo in photo viewer) around the screen, edit an image (crop, auto adjust etc) or just click to the next photo. When doing any of these I get large white lines/squares in the upper left corner of the image. This sometimes happens when playing games but occurs most often (all the time) when viewing/editing images. If I just view the image it is fine but the moment I move/resize the window or apply a filter and sometimes when clicking to the next image, the issue arises. I have tried different monitors and different image programs with no difference. I have also done a full uninstall and reinstall of the latest drivers from the AMD website (yes, I removed every trace of the old driver inc. registry entries). I have a dual monitor setup and disabling extended desktop does not solve the problem.
I have attached some images to help explain what I am talking about. I've tried googling with no avail as I don't even know what this is called, artifacting perhaps? Is this a RMA or is there a fix? Any help would be greatly appreciated as it's a real pain to edit photos when you have to keep clicking back and fourth between images to try and remove the squares.
