The bug is not in xfce window/compositor manager. Alpha transparency is
achieved by adding 8 bits for transparency (ie 24+8 bits) and some
applications are not aware or misuse this format.
VLC is buggy in this regard. Xine has been fixed, but not VLC.

The problem doesn't lie in xfce, sorry. That's why compositor is
optional and can be enabled/disabled. So, either disable it with VLC,
fix VLC, or use Xine ;)
