In bug 923961 in order to get OMTC (and therefore cross process compositing) to work, we had to introduce a fairly ugly hack in order to make sure that the b2g-desktop window we create is opaque. This bug should track fixing things "properly," that is to say without an #ifdef.

In bug 923961 comment 14, Markus asked why the code in nsContainerFrame::SyncWindowProperties didn't do the trick. The proximate answer is that there's a check in SyncWindowProperties that bails out if the given window is not a XUL window. As b2g no longer uses a XUL window, but an HTML one instead (see bug 894927) we never set the window's opacity. I don't know if fixing that alone would fix the original problem, but it's probably the easiest place to start.

MOZ_B2G is no longer found in nsCocoaWindow.mm.
