Thanks Daniel. I do think I have narrowed the issue down (at least in my case) to what John Moodie pointed out above. It seems to be some sort of polling issue - if a browser is trying to refresh something (causing a spinny wheel thingie) or Software Center is installing an application, it happens.
I've been able to minimize the issue by keeping my Chrome tabs under control - I think having a Facebook tab open (which seems to be constantly polling) was the majority of my issues. I haven't been keeping Facebook open in a tab, and the issue hasn't been much of an issue. I have found that if it crops up, a browser restart seems to resolve it. I can deal with this for now (since I think I understand what is causing it...which reduces frustration). And no, I won't switch...I just got back from a distro-hopping escapade - nothing touches the polish of Ubuntu or Unity, and I'm thankful for everything you guys do to constantly make it better :-) -- 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
