So if I understand this correctly, Firefox asks the hardware to render an image
way off screen? How come there isn't some fast rejection in place to clip the
part that won't be visible on screen anyway?

Are you saying that this is a bug in Firefox? Because they claim it's a buggy
XRender implementation...

So since other lemmings are jumping off a cliff.. :)
I think that if Chromium is able to run this demo at 10FPS in userland software
renderer, there must be some things that can be done to speed this up with
hardware access...
