Well, now you have a workaround.  One point for the good guys.

Do the ConfigureNotify events stop when you hide the GUI?

Unfortunately I know more about KDE's licensing than I do about its
internals, but I can't imagine that it doesn't use a separate process
for window management.

Hm.  I wonder what kicker has to do with all this.  If it's not the
window manager, I don't see why it would care about one of xine's
toplevel windows.  (Jumping to conclusions here, but since hiding the
GUI makes kicker cool off, I think the connection is pretty strong.)

    >> Do you know which window it is,

    Godwin> Do I know which window /what/ is?

The one getting all the ConfigureNotify events.  Looks like it must be
the GUI, but it's worth confirming.  You can check that with xwininfo,
which gives the window id.  Could you give me a few more of those
events, in sequence?  Alternatively, if they're all identical except
for serial number, I think we can conclude that there's a knockdown
dragout brawl over window configuration going on for some reason.
Also, can you see a flicker or anything like that in the GUI?  Does
the GUI have a dynamic display in it?

At this point, I have to think that kicker or the kde library
functions that handle window geometry are buggy.

What seems to be going on here (GNOME has similar problems) is that
the desktop environment developers design (or maybe it's simply a
subset of Xt) their own protocols for session and window management
rather implement the full Xt protocol exactly.  This results in
programs written with a different toolkit getting screwed, because
they don't use exactly the protocol that the desktop expects.
