I find that if I log out and back in too quickly, KDE does not load up
correctly either (though KDE is probably another beast compared to XFCE).

I noticed that KDE takes a while after logout to end all processes that were
associated with the session. Stuff like pulse and other daemons. So just out
of curiosity: before you log out of XFCE, log in remotely as root, open htop
and filter for your normal user (or use any other method of choice to show
processes owned by your user).
Now log out of XFCE. After a while, the filtered list in htop should be
empty (unless you set up some other background stuff that is independent
from any graphical session).
