Right, but taking a step back here: should we consider that as a bug?

IOW, instead of documenting workarounds, why isn't --maximized fixed to
not have the "slightly distracting visual effect"?  Is that impractical
for some reason?

Is this really about --maximized?  I thought this was about
customizations in the init file that cause frames to be maximized.

Thank you for assisting me Eli, that is exactly what this is all about.

To avoid the slightly distracting visual effect of Emacs starting with its default frame size and then growing to fullscreen, you can modify .emacs.d/early-init.el instead of .emacs (thanks Chad).

  (push '(fullscreen . maximized) default-frame-alist)

It works even if it takes time to load a typical .emacs configuration, and has been successfully tested in GNU/Linux (both X11, and Wayland), and Windows.

The push function in Emacs is used to add an element to the beginning of a list. In the _expression_ (push ‘(fullscreen . maximized) default-frame-alist), the ‘(fullscreen . maximized) list is added to the beginning of the default-frame-alist list. The default-frame-alist variable is a list of property lists that are used to configure the initial appearance of Emacs frames. Each property list in the default-frame-alist variable contains a set of key-value pairs that specify properties for the frame.

Essentially the code above will make emacs behave like `emacs --maximize` automatically each time when you open it, because the --maximize argument also opens Emacs without the slightly distracting visual effect.

I think I failed with the bold text, can you please rephrase it for me, Eli? I really want to use --maximize as a reference since it is inbuilt Emacs.

The --maximized switch creates the frame maximized from the get-go
here.

A few days ago I posted this:

I like Chad's solution to .emacs.d/early-init.el: (push '(fullscreen . maximized) default-frame-alist)

However, I'd like to compare it with the Lisp code that is executed by `emacs --maximize`, can someone please help with find it?

If it's better than Chad's solution, then I'm willing to update "To avoid the slightly distracting visual effect" (https://www.emacswiki.org/emacs/FullScreen#h5o-3) with code and a comment to the source file where this code is found.

---------------------------------->8------------------------------------------------

For starters, is it even possible to reuse all source code from --maximize in early-init.el or is it written in C?
