Screen snapshot: fading rendering

Having installed mesa 9. Compiz works @ ~5 FPS producing output as if one is
drawing in aquarelle on a wet paper (pls see attachment). Wallpapers are
rendered properly while all the windows are drawn this way. Meanwhile nothing
unusual were found in logs.

I installed it on Gentoo by unmasking my arch then update. It also required to
add libGLU. I tried few pre-releases as well as 9.0 on both 3.4 and 3.6 kernels
with the same result. I assume maybe some other changes are required I'm not
aware of.
Version of software are
media-libs/mesa-9.0
x11-drivers/xf86-video-ati-6.14.6-r1
x11-libs/libdrm-2.4.40
