I cannot reproduce this in "emacs -Q" with today's master. Do you
have any customizations related to scrolling? This further input from
you:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
seems to indicate that you have customized scrolling, because by
default Emacs does not scroll just one line. Perhaps you have
scroll-conservatively set to a large value; if so, I'd indeed expect
some slowdown when the font size is changed, because supporting
scroll-conservatively is sometimes costly, especially when the last
displayed line is only partially visible.
So please try this in "emacs -Q" first.
Thanks.
