xf86-video-ati-git, mesa-7.8.2, 2.6.34 with KMS, Radeon HD 3450 (studio 15).

Running gnome-shell-git (which uses Clutter, git version) results in pretty
much broken image (screenshot attached).
At gnome-shell irc, I've been told that "framebuffer objects" seem to be
broken. This can be tested by running Clutter test
"clutter/tests/conform/test-cogl-offscreen".

Here is a part of gnome-shell output, it actually contains lots of errors same
as following:


(mutter:9090): Cogl-glx-WARNING **: ./cogl-framebuffer.c:424: Failed to create
an OpenGL framebuffer
