xfce4/gnome + compiz - slow launch.

[Dmitry]

After installing compiz-fusion, xfce4 or gnome is launching very slow. Looks
like some timeout, xfdesktop is quite slow. Even when I don't start compiz,
this happens, but I don't start xfwm4 or metacity, so there are no conflicts
between WMs. When I logout and save current sessions with pidgin, and other
gtk programs, after login they start faster then xfdesktop. Any ideas about
it are appreciated.
