Qt4-X11 is using ARGB visuals, which seems like a logical thing to do if Cairo-Dock is running. VLC Xvideo and X11 plugins fail to handle this correctly when creating their rendering window. Thus, this is essentially a LibVLC bug.
A trivial work-around is here: http://git.videolan.org/?p=vlc.git;a=commitdiff_plain;h=c0ec5be56e71c273eef4faea8d927eeb3cbc7ec5;hp=493ed6ef7ff138e7b93f31e962bb28dfa06d928b
