Comment 36 for bug 190754

Gutsy had Jitter with O1 and ALSA when there was heavy load, like crypto disk R/W.
That problem is gone with Hardy - CFS really manages to keep sound stable in such sitations.

The interesting thing is that it only happens when minimizing/raising windows (especially from the notification area, no matter using Metacity or Compiz) - not when, say, looping the cover-flow task switcher plugin of Compiz.
