A few possibilities:

1.  You are using a video card and driver combination that doesn't
support hardware acceleration of the X Render extension.

2.  You don't have hardware Render acceleration enabled in your xorg
config.

3.  You're using the nvidia binary driver, which is known to have weird
CPU-eating effects on some platforms with some configurations with some
cards when the compositor is enabled.  (I was actually able to fix this
on my machine by messing around in my BIOS setup... I think I changed
"AGP Drive Strength" to... something else.  YMMV.)
