I also have a problems with cloud with Sandy Bridge (i965 driver), using linux
kernel 3.0 or 3.2, Mesa 8.0.1., see [1] in attached picture.

I tried with software renderer, still a little line under the clouds sometimes,
but far less. Some transparant textures like chimnees on roof  ([2] on attached
picture) have the transparent part fully black.

Only With kernel 3.2 (not with 3.0), that is far faster than 3.0, 2d windows
text rendering displays bugs during windowed flightgear ([3] on screenshot),
some times texte looks like barcode (vertical Black and white line along the
text), some time there is horizontal lines. hiding and redisplaying the window
resolve the artifact, but artifact appear again when the view is scrolled.

Still during windowed flightgear with Linux-3.2, jpeg display strangly in
firefox (4 ?, I can't manage to catch it in screenshot, when I click on gim
screenshot window, the problem disappear), pictures looks like randam shift
problems on some lines, like on old TV with bad signal reception.
