Note also that glxspheres still only runs at 3 FPS in Unity 2D, Gnome
Shell, Gnome Classic. So this is not a compiz-specific bug.

Confirmed with Intel Sandybridge graphics. glxspheres is stuck around 3
FPS.
However installing a _slower_ old nvidia card, glxspheres has no such
problem and runs smoothly.

glxspheres64 is using 100% of the CPU. callgrind shows all of this is
spent in:
100% intelBitmap
|- 100% _swrast_Bitmap
|- 50% intelSpanRenderStart
|- 50% intelSpanRenderFinish
I'm a bit worried about _swrast_Bitmap. Sounds like it's rendering in
software for some reason.
More profile details:
100% intelBitmap
|- 100% _swrast_Bitmap
|- 50% intelSpanRenderStart
|- 50% intel_miptree_map
|- 50% intelSpanRenderFinish
|- 50% intel_miptree_unmap
And both intel_miptree_map/intel_miptree_unmap call:
69% intel_offset_S8

Same here in Precise (updated).
Difference between 11.10 12.04 is huge.
I captured a screencast to illustrate the fps rates in precise.

I recall, in 11.10, my laptop's intel card ran glxspheres at 60 fps
while the discrete nvidia at about 140.

With compiz v 1:0.9.7.2-0ubuntu4 I now only get around half a frame per
second using the intel card. The nvidia card still runs at about 70 fps
using nvidia (less than half the speed it got in ubuntu 11.10).
