Description Harald Judt 2011-10-20 10:13:58 UTC
Created attachment 52601 [details] Screenshot with a corrupted terminal emblem. 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.

This was caused by enabling texture compression in core settings. Turning it off makes the icons look right again.

I think this might rather be a duplicate of bug 38173.

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.
