Unloading unity plugin and decorator makes no difference in my case. 64 bit with fglrx (Catalyst 11.10).
With top running in a terminal; 1: Open a browser, type a non-existent address in, such as http://non-existant-garbage.com Compiz and Xorg cpu usage spikes to about 50% and 40% respectively and will continue to remain there until the browser request is cancelled (or until there is no spinning load icon or mouse pointer change or the windows is minimised) 2: Open software centre and install a program. Compiz and Xorg will spike and remain high until the program has installed and there is no spinning progress icon in the top bar. Sounds like a polling issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/803943 Title: compiz consuming a lot of cpu To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/803943/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
