I don't know where this should go (drm, mesa?), but after a while, I notice corruption of textures / pixmaps. It can be reproduced quite easily by opening a few applications, or starting another X session. In particular, I could determine the following: - Corrupted areas resemble parts of the previous visible login screen - Icons, fonts and widgets like vertical gtk progressbars get corrupted, but only their lower half - Window (emerald) decoration seem to get corrupted completely. - It's not related to color tiling. - Pageflipping is enabled. - Restarting a corrupted application fixes it temporarily, while minimizing etc. doesn't. Restarting compiz doesn't fix it either.
I believe this is specific to cayman, as the issue does not occur on a thinkpad t400 with ATI Mobility Radeon HD 3400 and similar configuration.

Apart from this, it works great, no crashes so far!
