Debugging X server's CPU burning

Hey guys,

We have a web page on our intranet - it's an employee photo gallery.
The page isn't terribly complicated and loads in Mozilla in a second
or two.

While the page is open, the X server burns 100% of CPU even if no
scrolling is happening.  If I had to guess, there may be something
rendering on the page.  I noticed this when a co-worker commented that
it behaves normally with Mozilla on Windows.

I'm not really familiar with debugging X applications - how would you
guys suggest I start tracking down what the bad behavior here is?

"The good Christian should beware of mathematicians, and all those who
make empty prophecies. The danger already exists that the mathematicians
have made a covenant with the devil to darken the spirit and to confine
man in the bonds of Hell."
	--St. Augustine, De Genesi ad Litteram, Book II, xviii, 37
