With latest kernel 3.12.0, mesa 9.2.2 and ati 7.2 color corruption mostly
disappeared with the Native KDE backend and OpenGL 2.0 selected.

Although, every couple of seconds (every ~2-3 sec) my desktop lags for a
moment, using `perf top` I see:
 45.08%  [kernel]                 [k] radeon_vm_bo_set_addr 

which stays like that all the time. The desktop is pretty much usable, but
watching a HD movie is almost impossible with all that lagging every few
seconds.

Gentoo + HD7870 here.
