I've been editing on a friend's system for the past few days under a newly created account on their Mac. We've been using Fast User Switching a bit and I've noticed that if I leave FCP running on my login while my friend logs into their account, when switching back to my account sometimes, but not always, the Canvas will display heavy artifacts and skip considerably while playing something from the timeline. The footage was shot to a P2 card as DVCPro HD, 720 24p.
The odd thing is it's not consistent and I can't reproduce it every time at least so far. It may have something to do with this little-acknowledged Quicktime bug 7.4.5 but I'm not sure. Another report of this bug is here.
