Is this a hardware issue? It seems like after I reddit for awhile, large images will start to scramble in little tiles of precision sky viewed images. It's hard to describe and next time it happens I will photograph it. It also happens sometimes when editing images in photoshop. I have AppleCare, so if it is hardware, I have a few months to bring it in. The problem is that I can't reproduce the issue on command. I'm unsure if what to do. Is this normal for 2011 MacBook Airs, do you think it's an issue that needs to be fixed?
