From much mucking about, I have decided that to fully reproduce this bug requires the below.

Ubuntu 8.04.1 2.6.24-21 64-bit
nvidia-glx-new 169.12
With Xinerama enabled in xorg.conf.

All programs run sluggish including:
Firefox Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.3) Gecko/2008092510 Ubuntu/8.04 (hardy) Firefox/3.0.3

My cards are 8800GT and 8500GT with 4 monitors.
Perhaps mismatched cards are the culprit. They seem to run fine in Windows Vista (64-bit)

The fix above definitely sped some parts of the gui up, but slowed all the javascript way down. To the point where I couldn't move the cursor to another monitor for several seconds.

I can post more configuration files and whatnot if anyone is interested.
