> An emacs session that never uses CTWM's `toggle zoom' to "maximize"

Could you please explain how that toggle works and how an emacs session
can use it?  IIUC without it you see the problem below.  With it you
don't see the problem.  Does it have any detrimental side-effects to set
that toggle?

But this is a difference of 8 pixels and nowhere near the 50 pixels you
mentioned earlier.

Not really IIUC.  The 'fullscreen' status is reset in either case.
