Lithic Rune

Ever since I got this computer, the amount of time I've spent using Photoshop has gone drastically down. The reason for this is because Photoshop apparently hates my computer. It is really, really irritating to try to edit or color something when random bars of inverted color crisscross the picture, or I can't see the edges of the image because of some weird doubling effect. And then there's the issue of the image "smearing" when I use the hand tool to move my view.

I do not think words can accurately describe how frustrating these glitches are. What's needed here are pictures. And so, jury, I present the evidence!
