Here compiz/kwin crashes when tries to run with weird assertion on msaa
textures. 
Found that msaa can be swithced off with enviroment variable 

http://cgit.freedesktop.org/mesa/mesa/commit/?id=1d0bf69f831e138a05a282e59746f20141046fd6

but GALLIUM_MSAA = 0 doesnt help at all.

so I edited dri_fill_st_visual in dri_screen.c to disable msaa at all 

   if (mode->sampleBuffers) {
-      stvis->samples = mode->samples;
+      stvis->samples = 1;
   }

Now compiz/kwin work fine.

kernel 3.8-git from ubuntu daily kernel-ppa, ubuntu 12.10, nvidia gtx670
