I finally managed to capture a very brief screen print of the pixelation/scrambling of my screen upon opening thunderbird while firefox is open. if you look at the bottom right hand side of the frame, you can see a tiny amount of it. it's been worse than that but at least you can get a sense of what I'm talking about.
