Comment 4 for bug 949958

I'm also having corruption on open ati drivers between pressing enter on password and desktop showing. However, it's not checkerboard for me, and there are a couple variations - corruption at top/bottom with image shifted a bit, black-and-white coloring but no corruption, or black-and-white with items moved to right and some corruption. Pretty random, anyway, and probably same cause of messing image/texture data somewhere.

Adding three pictures, which are ~full screen photos (screen frame visible in some of them) that are unmodified _except_ for the white rectangles where I just removed the other user names. Everything else happens on the screen.
