Fullscreen apps problem

[Ben Davis <ben xsusio com>]

I have a lot of problems with my window manager (metacity) when it comes 
to some fullscreen applications...  For some reason, when an application 
attempts to go fullscreen, the window manager takes over and still put 
decorations on the window.  The only way I can get it to true fullscreen 
is to have to go the extra step of using the feature of metacity that 
lets you maximize the window and remove the border (i.e. the keybinding 
for "fullscreen" mode)...    Strangly enough this doesn't happen with 
all fullscreen apps, mplayer and frozen-bubble seem to know how to get 
around this but other fullscreen apps do not (such as mythtv).

Should I file a bug on this or is it already out there?
