After emacs -Q

Open font dialog

How do you open that dialog, exactly?

This is macOS specific, because I don't see anything like that here.

Thanks.

Not only that, but it also shows up on every other Mac OS app when
opening the font dialog.  So let's sue Apple for their illegal
activities.  (Doesn't this joke ring a bell? I think this bug report is
a duplicate of another, but I can't find it.)

Yes, it's a duplicate of bug#56259.

Thanks, I've merged the two.

bug#56259: 29.0.50; Illegal -layoutSubtreeIfNeeded on NS

[Gerd Möllmann]

On macOS 12.4, selecting Options -> Set Default Font from the menu bar 
reproducibly prints a message to the terminal:

emacs[76309:7042282] It's not legal to call -layoutSubtreeIfNeeded on
a view which is already being laid out.  If you are implementing the
view's -layout method, you can call -[super layout] instead. Break on
void _NSDetectedLayoutRecursion(void) to debug.  This will be logged
only once.  This may break in the future.

Hopefully nobody get's sued because of that illegal action...

I think the general consensus was that this message is a bug in some
Apple framework and not in Emacs, so I'm closing the bug report.
