Thanks for submitting this report. I was able to reproduce this behaviour on feisty with the steps explained. I did not get 95% cpu load, however, xorg used between 50-70% and firefox >15% on the webpage, while being 0% when I go back to the default homepage.
There is some javascript on the site, however, on dapper both firefox and xorg use far less then 10% each. There is a distict difference on feisty. ** Changed in: xorg (Ubuntu) Status: Unconfirmed => Confirmed ** Summary changed: - Xorg server up to 95% of CPU + [feisty beta] Xorg server up to 95% of CPU ** Tags added: feisty -- [feisty beta] Xorg server up to 95% of CPU https://bugs.launchpad.net/bugs/104481 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
