Is this what's happening here? If you compile emacs-28 with tookit=lucid
and separately with the default (tookit=gtk3) and compare the two emacs
-q --geometry 83X37 you get different sizes. The gtk3 emacs is slightly
taller than the lucid version. I attach a screen shot. On the right is
lucid and on the left is gtk3. The tool bars are of slightly different
height.

I apologise if my intervention is a irrelevant.
