Comment 0 for bug 1378795

I am using Ubuntu 14.04 on HP workstation with Nvidia GH9600 card and latest drivers..

I've been trying to figure out what is causing my Xorg and Compiz to frequently come close to maxing out my CPU usage for weeks now. Essentially, during normal use, both processes will fluctuate between using next to no CPU to all of my CPU. Does anyone know what could be causing this issue, and how I could go about fixing it?
