Programs using X freeze while switching windows

Olivier Fourdan <fourdan at xfce.org> had occasion to say the following:

Sorry, but I don't understand your post.  I'm running xcompmgr from CVS
also, so the code is quite up-to-date and I don't know what you mean by
fixing it.

On the other hand... Xfwm is using its own compositor?  (Who knew?)  How
do I get to it?  I don't see any commands to activate it (using today's
CVS), nor have come across any documentation of such a feature.

Thanks,
Andrew
