Subject: 30.0.50; [pgtk] Theme customization is not applied by
 custom-theme-set-faces until theme is re-enabled
Date: Fri, 2 Feb 2024 01:14:12 +0200

To reproduce, put this into .emacs:

(add-hook
  'after-init-hook
  (lambda ()
    (load-theme 'adwaita t)

    (custom-theme-set-faces
     'adwaita
     '(font-lock-comment-face ((t (:foreground "yellow")))))))

Then run emacs -Q.

When the PGTK port is used, the comment face's foreground won't be
yellow. With other ports (e.g. GTK3 or Lucid), it is.

The use of after-init-hook itself it not crucial - you can just as well
enable the theme using 'M-x load-theme' and then evaluate the
custom-theme-set-faces form.

There is some text on the splash screen with font-lock-comment-face
applied, so you should see the effect right away.

Upon rereading your description, it appears as though you're reporting
that `emacs -Q' does not load the user's initialization files, while it
does in the non-PGTK builds.  Needless to say, if true, that is a severe
bug!

I can reproduce this, thanks.

Not sure it relates to the user initialization files: like I say below, 
the same scenario and the result can be reproduced interactively after 
Emacs has initialized.
