Xine + Multiple Desktops = Lockup

[smcallis182]

I've been using xine to watch a couple dvd's lately, and I've noticed that whenever I scroll to another desktop (I'm running 4 virtual desktops in FVWM), my system stops responding. I can hear the playback audio stop and then I can't scroll to any other desktops, close windows, anything but move my mouse around basically. I'm running Xorg 6.8.0 and xcompmgr is that makes any difference. Has anyone seen this kind of behavior before? I should probably note that I've seen this same behavior in Mplayer, so I doubt it's application specific, more likely something to do with how they're displaying content to the screen... Ideas?
