Comment 21 for bug 1293384

OK I think the problem is much worse than I originally thought. Even moving around the mouse causes massive CPU usage.

For example, launch Nautilus, and move the mouse around inside it for 15-20 seconds or so. CPU usage jumps to 25% each for Xorg and nautilus, and 15% for compiz. Similar results occur for any other program like say Firefox.

I'm really getting horrible all-around lagginess out of Ubuntu 14.04 because of this out-of-control CPU usage. I don't understand why there aren't widespread complaints about this? Is it only affecting a small portion of users?
