Re: wine's fullscreen code has no effect on metacity

Some patches were committed to wine recently to make it use

metacity, it appears wine recognizes that it needs to make a window
fullscreen and send the appropriate message, but nothing happens
(panels are still on top of firefox in fullscreen mode).

I've mentioned this on wine's bug

probably caused by some quirk in metacity that wine triggers by doing
some rather odd things itself. That's why I've CC'd the metacity-devel
list (to which I and probably anyone on any wine mailing lists are not

So, uh, metacity people, under what circumstances would metacity be
likely to put a window that had sent the proper _NET_WM_STATE_ADD
message for _NET_WM_STATE_FULLSCREEN behind panels?

If you have properly changed the fullscreen state as it sounds, the
only case in which metacity ignores this hint is when the window
doesn't have focus and is on the same xinerama as the window that does
have focus (this is to allow the user to alt-tab to another window and
do something without having the window they alt-tab to just remain
covered up).  So, if you can run
  xprop | grep _NET_WM_STATE
and click on the relevant window and it shows
"_NET_WM_STATE_FULLSCREEN" as one of the states and then focus that
window and observe it to not be on top of all other windows (including
panels), then it sounds like you've discovered a bug in Metacity.  If
so, I would be interested to learn how to reproduce so that I can fix
