[Bug 861061] [NEW] compiz 3d performance regression


Public bug reported:

A recent update to compiz in oneiric has had a big impact on 3d
performance. The desktop feels more sluggish, and the glxspheres
benchmark indicates about half the performance compared to metacity and
mutter (on my Sandy Bridge GPU I get 30-32 fps in unity/compiz vs 59-60
fps in both unity-2d/metacity and gnome-shell/mutter). Previously compiz
matched the performance of metacity and mutter.

I also tested the oneiric beta2 live CD (amd64) and performance was
similar (ie regressed compared to beta1).
