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. ** Attachment added: "Example of site triggering the slow rendering." http://launchpadlibrarian.net/15027037/SlownessExample.zip -- firefox 3.0 very slow on some sites, blocking computer https://bugs.launchpad.net/bugs/232197 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
