I'm seeing the same behavior on some sites. The scrolling becomes so slow that the browser freezes for 1-2 seconds whenever you do. If you hit the clickwheel a few times, it's enough to trigger the "unresponsive application" warning, while the browser uses 100% CPU to redraw the window.
I'm using Ubuntu 8.04 in AMD64, up to date as of now (June 5th). Kernel 2.6.24-18-generic, Firefox 3.0~rc1+ nobinonly- 0ubuntu0. 8.04.1, Xorg 1:7.3+10ubuntu10.1. I have Compiz enabled with nVidia proprietary driver (169.12).
I'm attaching a test case which is pretty painful for me with Firefox 3, but which renders fine on Ubuntu 7.10 with Firefox 2.
I suppose this bug is related to the Gecko engine, since epiphany-browser also exhibits it. I also suspect Bug #207454 is related to this one, but this seemed more general, so I'm posting here.
