Frankly, I don’t know how to check whether Emacs uses Xwayland. If
I compile with --with-x I would expect it to do always, but is this
the case?

What I do is pretty crude: I make a screenshot and look at it in
Gimp heavily magnified. With pgtk, I see only greyscale at the rim
of the glyphs, and without pgtk, I see pixels of various colours
(greenish/reddish). This coincides with my subjective observation
that in the latter case, the text is crisper.
I do see subpixels in the menu text of other applications as well as
in the Chromium browser, in the same Gnome session as Emacs.
Regards,
Torsten.
