Every now and then, but typically daily, my monitor looks like it is going to break in half. It only happens when I have my laptop hooked up to my Apple Cinema Display. But I don't think it is a hardware issue. I am convinced it is a graphics card issue, associated with a software OS update.

When I use programs and they overlap, and my computer runs slow. Sometimes the windows skid on each other causing parts of the screen to look like they are tearing apart, or sometimes even a white TV screen fuzz look. Here is a picture of the weirdness:

Honestly, it doesn't bother me that much. It goes away as soon as I move another window on top of it.
