--- Comment #10 from Cùran debian@carbon-project.org 2009-10-15 18:43:49 --- For me the corruption is gone with 1.1.29 (from Debian Sid, the rest is a Debian testing system). But this might also/solely due to a new version of Mesa (7.6). In my case, that brought OpenGL support to 1.5.
Now it just seems to be slower than software acceleration. Can't be too sure though, as I didn't have time to test it thoroughly.
