I should confirm this too. As a matter of fact, even when kms is disabled, the video is somewhat slower than it used to be on koala. For instance, switching windows is rather sluggish. This last one is probably related to the the poor memory management.
Well, this issue is nothing compared to the main issue - regular system freezes. Is it a different bug?
