--- Comment #7 from l55@anonymousspeech.com ---
i installed kernel 3.18.2 and upgraded mesa and the other packages except for
libdrm-radeon1,xserver-xorg-video-ati,xserver-xorg-video-radeon from the
mentioned oibaf ppa.
Now DRI_PRIME=1 esgears displays fine, but fps are not higher than with
integrated(the same fps) and unigine tropics benchmark is still corrupted.

I tried to run a game with wine on the gears on gallium livedvd and the fps, if
i recall correctly, were lower on the dedicated gpu than with the integrated
but no corrupt display there(didn't test es2gears/tropics with it because
es2gears is not included(tropics benchmark may be included in phoronics test
suite, i'll check that) and the livedvd doesn't seem to have a package manager)

gears on gallium 2014.12.25 packages:
Mesa-git – 10.5_git2014.12.25
Kernel – 3.19-rc1
libdrm – 2.4.99_git2014.09.30
Mesa-demos – 9.1.0_git2014.07.06
xorg-server – 1.16.99.9
xf86-video-ati – 7.99.99_2014.12.20
