Am I the only one with serious radeon compositing issues? I have:

08:00.0 VGA compatible controller: ATI Technologies Inc NI Caicos [AMD RADEON HD 6450]

gnome-shell is painfully slow. Cinnamon draws its desktop overview at about one frame every three seconds.

Are you sure you have the radeon firmware blobs installed and properly loaded by the DRM module? Without them, you won't get properly hw-accelerated OpenGL on many of AMDs more recent GPUs.

Updating drivers to git from today fixed it. Tiling makes a big difference on low-end (and thus low memory bandwidth) radeons, apparently.
