Same problem HP dm1z-4100 (amd e-450)
Setting "Force full screen redraw (buffer swap) on repaint" seems to improve performance overall, compiz normally uses 60-80% cpu when moving a window (crazy right?) and when set "Force full screen redraw (buffer swap) on repaint" it uses only ~30%.

Also the cpu usage is near zero % when the screen is off with the "Force full screen redraw (buffer swap) on repaint" option.
