For a couple of weeks now I've been getting artifacts everywhere in my computer. It may have been after a driver update, but I can't tell for sure, since it doesn't always happen and neither do they appear in the same places. Checked several times and updated to the last amd Crimson drivers. I'm running two monitors, one with Radeon R7 260 and a second one with integrated Intel(R). The only one which seems to be experiencing these issues is the first one, the one hooked to the AMD display, tho I've seen it happen on the second one maybe once. The artifacts appear as checkered blocks which seem to try and refresh when I scroll the window or move the camera on games, sometimes disappearing, sometimes coming back. I don't have any screenshots of it since it's not happening right now.
Hope this is enough for someone to help me out. Thanks in advance!
