I can confirm this exact same behaviour. White static on a 1920x1200
resolution, doesn't happen in 1680x1050, 1600x1200 or below. Doesn't
happen either on Intrepid + fglrx, or Windows XP. Since I also have the
"flickering" bug (sometimes, screen switches off for one second), I
tested if the CPU frequency changes anything, but it doesn't. Flickering
is not noticeable on a white background, and barely noticeable on a
black one. Also, it isn't a heat problem, since it also happens right
after a cold boot.

jMax's description of this phenomenon as "static" is quite good. It
consists of lines that are always horizontal and seem to be one pixel in
width and varying between ~5 to ~50 pixels in length. They are white,
although some seem to be reddish. It is a little hard to make out, since
they disappear almost instantly. They are not related to any windows or
other area of the screen.

My Xorg.0.log contains the same warnings as jMax's, but not the error.
