Unfortunately this did not solve the problem.

And I noticed something: comparing with and without cairo, even though
the number of lines of text and other geometric parameters are
identical (no .Xdefaults or any changes in .emacs.d/, the window
(frame) height for with and without cairo are different.  Something
about font handling are different?

Thanks,
