I KNOW WHY THIS IS HAPPENING The firefox "Throbber" icon causes 100% CPU load with Xorg when running compiz as pages are loading. You can disable the main throbber which is completely pointless anyway by dragging it off the menu bar using View --> Toolbars --> Customize
But there is no way I know of removing the throbbers from each tab which also eat 100% CPU each -- Firefox 3.0 beta 5 40% and 70% CPU AND Xorg 50% and 40% https://bugs.launchpad.net/bugs/248271 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
