Comment 57 for bug 1293384

I though i should share this here, since i was plagued with this bug on Ubuntu 15.04. No matter what i was doing, if i moved a window around, the cpu usage of xorg skyrocketed to 100%.

Nothing worked for me. But then i found a solution: Just go to compiz settings --> Windows Management --> Move Windows and ENABLE Lazy positioning. That's it, problem solved.

Hope this is helpful for you guys.
