Confirming this happens also for me in Jaunty on two PCs: a laptop using the "intel" driver, and a powerpc64 using a nVidia card. In both cases lesser artifacts are seen in *every* page you visit.
I have to add that other problems have arisen also for other parts of the desktop using gtk+ & cairo for rendering (icons in gnome-panel, toolbars in applications, widgets, etc.), so it's not related to firefox imo. Mostly the problem seems to arise when using pixbufs (?).
