this is a solution that works on archlinux really well, and maybe would work for your system too
then reboot or restart x serverCode:echo "export CLUTTER_VBLANK=none" > ~/.profile
I to have been experiencing the same problems, and have tracked it back to possible kernel problem. I have check and top and compiz are using a very large amount of memory and cpu. It's not just AMD drivers or any other problems. Many different CPUs and video cards have been tested and it's not any one system. There have already been a number of bug reports on this.
I had to resort back to using OpenBox, and still my CPU usage is a bit higher then normal.
Your issue could be due to a number of causes. I pulled my hair out trying to solve an issue with identical symptoms to yours not that long ago. Dragging windows resulted in visual stuttering under compiz. The root cause was that I had a super-de-duper-gee-whiz mouse (RAT 7), and the high polling rate was causing compiz to resync a thousand times per second. Manually reducing the mouse polling rate (or using a cheap mouse) resolved the issue.
Give it a shot if you have a high resolution mouse.. It's a simple cut/paste to the terminal to try it out. You can set it at boot/login using whatever method suits your distro and disposition.
