Using compiz-0.8.8 ring switcher or scale plugins, the emblem icons (=icons at the lower right of the windows) are corrupted. They look fine on pre-cayman hardware. See the screenshot(s) attached.

probably a duplicate of bug 38022 or bug 40221.
Comment 3 Harald Judt 2011-10-24 11:25:31 UTC 
This was caused by enabling texture compression in core settings. Turning it off makes the icons look right again.
Comment 4 Harald Judt 2011-10-24 11:58:24 UTC 
I think this might rather be a duplicate of bug 38173.
Comment 5 Harald Judt 2011-12-06 04:43:47 UTC 
This problem is still there in linux-3.2-rc4, and clearly related to using s3tc libtxc_dxtn, as it does not happen when the library is not available.

Fixing this would also make it possible to play games on cayman gpus that require s3tc.
