That is in fact a different issue, although it might still be helpful in
working around it by making those windows not get inserted below others.
The "flickering" is probably that vlc expects the window to be on top and
focused, and withdraws and recreates it if it isn't; you could probably use
something like xscope / xmon / xtrace (seems like every Linux distribution
has only one of the three, and probably there are others out there that
something has decided is the right one to the exclusion of the others...)
to verify, if you're somewhat familiar with the X11 wire protocol.

ComposeOne is from
http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Hooks-ManageHelpers.html#v:composeOneand
allows you to specify that only one hook out of a group should run; so
you can match the vlc dialog (use xprop to determine how to recognize it)
and handle it normally to avoid vlc's misbehavior, and push other windows
down.
