My laptop has an integrated Intel HD 3000 card. I have uninstalled the nvidia and nouveau drivers for reasons. With a single monitor, I dont see a CPU spike when using Alt-Tab. With 2 monitors, Alt-Tab causes a CPU spike to 50% on all my 4 cores. I can reproduce this at will and can see the spike clearly using htop for each of the 4 cores. CPU continues to stay at 50% on all the cores if I dont release Alt-Tab. As soon as I release it, the CPU drops back to 3% on all the cores. Is compiz the culprit ?
