Ah, yes that would be Lucid.

That's fair, but my intention wasn't so much a comparison with GTK3 as a
question for how [P]GTK3 should work in Emacs.  Let me know if I should
take this elsewhere.

Okay, but what alternatives are there?  I have the following directories
under /usr/share/themes: Adwaita, Adwaita-dark, Default, Emacs,
HighContrast, Raleigh.

Replacing Adwaita with Default, Emacs, or Raleigh in settings.ini makes
no difference.

With Adwaita-dark, I see the following:

[2021-02-14-124035_722x180_scrot.png (image/png, inline)]

[Message part 3 (text/plain, inline)]

And with HighContrast seeing is not believing that the region is active:

[2021-02-14-124234_717x176_scrot.png (image/png, inline)]

[Message part 5 (text/plain, inline)]

Is this entirely a misconfiguration on my end, or can Emacs do better?

Thanks,
