Created attachment 16889 [details] oprofile results using kompmgr (kde3) and EXA acceleration
Created attachment 16890 [details] oprofile results using compiz and EXA acceleration
The compiz profile indicates your Mesa and/or xf86-video-ati is too old for zero-copy GLX_EXT_texture_from_pixmap. For kompmgr, you'd have to track down why it's falling back to software rendering, though again it might make sense to try newer upstream versions first.
Is this still a problem? Closing under the assumption that it isn't, per Michel's comments. Reopen if it is. Whatever the case, Acceleration/XAA is not the right component.
