You get the same in a non-pgtk built, too -- and I think that's to be
expected?  Emacs first pops up the frame and then starts doing the
--eval stuff, I think.

If you want to set the background colour in this manner, putting it in
the early init file should do the trick, if I remember correctly.

So I think everything here works as designed?  Anybody have any comments
here?

Yes.

To summarise -- to avoid the flashes, you have to put something like

(add-to-list 'default-frame-alist '(background-color . "#000000"))

in the early-init.el file.  So I think everything works as designed
here, and I'm therefore closing this bug report.

I originally reported this issue via email to emacs-devel.
Stefan suggested that I try early-init.el and suggested
that a bug report would be more appropriate.

I attempted to use early-init.el without success and
so set about to submit a bug report.

My previous erroneous repro case

    emacs -Q --eval '(set-background-color "#000000")'

was an attempt to comply with the advice in the bug
template which asks for a -Q repro.

That said, the sub-optimal behavior is real:

* early-init.el:

    (custom-set-variables
     '(default-frame-alist
       '((fullscreen . maximized)
         (background-color . "#000000")
         (foreground-color . "#ffffff")))
     '(inhibit-startup-screen t)
    )

* init.el:

    [EMPTY]

This time, before being so quick to close, please
confirm that any suggested fix actually works.

My confusion about sequencing makes me think that
there might be a place for an --early-eval option.

Ah, I see.  OK, reopening.

I'm unable to reproduce this with or without pgtk -- Emacs doesn't flash
the default background colour on startup, as far as I can tell.  (This
is on Debian/bookworm with Gnome Shell, if that matters.)

Isn't it true that to have the initial frame appear from the get-go
with some non-default attributes, one must change the X resources?  I
have a vague recollection that this was always like that, and was
never perceived as a problem.  How do you want Emacs to perform the
initialization without first creating a GUI frame, and how can it
create the first GUI frame except with the default attributes?

I apologize for the tone of my most recent note.  My experimenting
was flawed.  When I hide my init.el I failed to delete init.elc.  Once
I deleted it my pgtk build performed as expected.

I have closed the bug.

In times past I did indeed establish X-resources.  Those are no longer
necessary.  I do not recall when I ditched them.  Perhaps it was around
the advent of early-init.el.
