I have tried out several different fonts but there is no change to the
problem.
I still see the circles. These can be turned off if I turn off
auto-composition-mode. However, though the circles then disappear, the
vowels appear incorrectly placed. They are not as poorly placed as
before, but still do not all properly align beneath the consonants. Some
vowels are slightly off.
I added (add-to-list 'default-frame-alist '(font-backend xfthb)) to my
.emacs file, but this made no difference.

I see circles on my GNU/Linux box, but only when using the xft font
backend, eg the second character from the left (visually) on the
'Aoristic perfect' line. If I put
(add-to-list 'default-frame-alist '(font-backend xfthb))
in my .emacs, then everything displays correctly.
That's what I thought, thanks. So these circles are a deficiency of
FLT shaping.
I thought HarfBuzz was supposed to be preferred to xft?
It's supposed to, but, disappointedly,
https://lists.gnu.org/archive/html/emacs-devel/2019-06/msg00124.html
remains without a response, and therefore only the Windows build
currently prefers HarfBuzz. I still hope Yamamoto-san will respond
and describe his proposal, and we could then implement the same
behavior on all platforms.
