I ran into this issue only today. On my display which is just a 32in tv (saving to upgrade) I have pink pixels that are constantly popping up.Another thing that happens is some text and images will stretch out. Today I finally decided to update my drivers to the latest software (17.2.1) and this when the problems started. I did a clean uninstall of the drivers and the glitches went away. However, when i re-installed them the issue returned. While play games there arent to many issues but there is stretching of some textures. Browsing the web and watching videos is where most of the glitching occurs.
