I have been noticing strange pixels forming patterns when I have an all black or white image. I took a picture of it, and you can see it from the photo. It looks like a red pattern across the screen and it actually moves with the application if I grab the window and move it around. Here is a photo with a box around the problem. http://img835.imageshack.us/img835/9843/atierror.jpg Not sure if it's bad ram on the card or something else.
