(A small note that Stavros' comment was to bug #340578 getting fixed he was experiencing and I was also experiencing a year ago, not actually this bug. I wrote to him: "I remembered a wrong setting that fixed my "1 fps" problem earlier. It was disabling the sync to vblank in compizconfig-settings-manager")
Virgil: Just to make sure, observe the CPU clock speed when eg. doing a lot of scrolling. If it doesn't increase from the minimum MHz, it might be the same problem as I was having. Otherwise I will stop commenting on this bug report :)
