[screenshot](http://imgur.com/0y8qy) So I have this really awkward bug with my app switcher. I recently just did an overhaul on my Mac, new Corsair Force 3 128GB SSD, Samsung Spinpoint 500/7.2k HDD and G.Skill RAM. Prior to these upgrades I was running a stock 2010 MBP 15 (Macbook Pro 6,2) on Lion with no problems. I did a completely clean install when I got the new stuff. The bug seems to only affect the app switcher and I have not noticed it anywhere else.
