Public bug reported:

Binary package hint: compiz

Desktop effects are noticeably slower while Firefox is open. My display
adapter is an integrated Intel® Graphics Media Accelerator 4500M. I
tested this using the built in Benchmark plug-in.

When Firefox is not running I get a solid 60fps (vsync is enable I
believe). Having a few GTK+ applications (such as nautilus, gedit.. etc)
open does not slow the frame rate even when running the expo plug-in.
Running Firefox causes a noticeable slowdown in the expo plug-in and
desktop switching. The frame rate drops to 30fps and below and feels
choppy.

I have not modified the configuration of either compiz or my intel
driver. I am running Lucid on AMD64. This occurs on both the Generic and
the Preempt kernels.
