I will need snapshots of all you see, because I cannot even begin
debugging without seeing the exact pictures.

Mode line is not handled in the patches I made, so it's little wonder
you see what you see.  (Does someone actually use Latin Modern Math as
the default font? it's an ugly font, AFAICS, and I expect it to be
used only for math stuff that the main font doesn't cover.)

Any special character you see look bad, please make sure with "C-u C-x ="
with which font it's displayed.

Recipe, please.  Starting from "emacs -Q", as usual.

> And the header line is tall.

That's the same code as for mode line, so it's expected.
