I wonder if anyone is seeing something strange going on in the Finder window. When I use List View and scroll up or down, the file and folder names become unreadable and I see a checkerboard-like pattern. The image below illustrates the problem. If I scroll away from this area of the finder window or resize the window, sometimes it clears up on its own. Genius Bar is going to replace the Video Card but since this ONLY happens in Finder, I'm not sure that is the problem. Anybody else seeing this.
