Firefox right now assumes that it has the full width/height of the toplevel window to draw its content into.  Normally this isn't a big problem, even though it's incorrect, but we're adding [optional] support to GTK+ now for doing window decorations on the client side [*], and when that feature is enabled Firefox often looks incorrect.  It draws the content at the correct [x,y] for the bin->child, but the content appears to get clipped by the right/bottom edges of the window.

I looked into this a little bit awhile back and it seemed that there was a certain point where the window gets its XID from the GdkDrawable and passes that to the drawing surface, which obtained the width/height from the XID.  I don't remember the exact details now, and I'm not very familiar with the Mozilla source code.

Also it should be noted that some windows behave differently than others, and I never discovered why.  The main window seems to correct itself when it receives a configure event, but the "about" dialog never gets corrected.
