I am using Ubuntu 12.04.
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.
I did a little research and it might be a memory leak, but I'm not entirely sure. Does anyone know what could be causing this issue, and how I could go about fixing it?
I'm using an ATI Mobility Radeon 5400.
