Yes, I forgot to say: This is all about fullscreen frames.

You never use them. I use fullscreen exclusively, for Emacs.

When I am in Emacs (which is all day every day), I just want Emacs in
front of me. No menu bars, titlebars. or anything!

Firefox does the stupid effect in full screen mode, too, turns out.
So we can't look there for the answer.

I don't think the correct solution is to change a setting on the OS,
since railwaycat Emacs does the right thing without external adjustments.

This bug is in fact what has kept me on his hacked Emacs all these
years. But due to other bugs I have been forced to upgrade to Emacs 30,
and I don't think he's going to update from 29.

Looking at nsfns and nsterm 29.4 vs. 30.1 I don't see anything that stands out.

Where did you get your 29.4 and 30.1 builds?

The bugs forcing me to upgrade to 30.1 are entirely unrelated to windowing. (Just other things that were broken and recently fixed.)

Windowing system distributor 'Apple', version 10.3.2113
System Description: macOS 12.7.6

Emacs 29 is the railwaycat version from Homebrew.
This has the behavior that I want (no effects).
brew tap railwaycat/emacsmacport
Which supposedly comes from: https://github.com/railwaycat/homebrew-emacsmacport
GNU Emacs 29.1 (build 1, x86_64-apple-darwin20.6.0, Carbon Version 164 AppKit 2022.7) of 2023-08-08

Emacs 30.1 I got from: https://emacsformacosx.com/
(I wish I knew who that entity is. I wonder if it has malware.)
GNU Emacs 30.1 (build 1, x86_64-apple-darwin18.7.0, NS appkit-1671.60 Version 10.14.6 (Build 18G9323)) of 2025-02-24

Is there an easy way to tell what compiler options were used on these builds? (Maybe some emacs command will tell me?)

It doesn't really take much effort to click around Caldwell's site and find out more. You should.
