Mozilla's HWACCEL demo is much slower for me with layers.accelerate-all on than with layers.accelerate-all off. I get ~15 FPS with layers.accelerate-all on and ~90 FPS with layers.accelerate-all off. Other websites demonstrate a similarly drastic slowdown as well.

Reproducible: Always

Steps to Reproduce:
1. Toggle layers.accelerate-all
2. Restart Firefox
3. Observe speed difference
Actual Results:  
Compositing is much slower than XRENDER acceleration

Expected Results:  
Compositing should match or exceed XRENDER acceleration in speed

I am using a nightly from Dec. 2. I have a GeForce GTX 285 with nvidia blob 260.19.21 drivers. I am using a current ArchLinux installation with kernel 2.6.36.
