When setting the a font on a frame after a resize, there is an apparent
race condition that more often than not, causes the frame height and/or
width to be reset to an incorrect value.
This behaviour also occurs on 24.3.92.
1. Create a file bug-frame-resize.el with the following contents
(assuming that Courier and Monaco are present on the system).
(setq -last-used-font nil)
(setq -target-font-1 "Courier")
(setq -target-font-2 "Monaco")
(setq -target-height 5)
(setq -target-width 5)
(defun bug-frame-resize ()
(interactive)
(with-selected-frame (make-frame)
(set-frame-width (selected-frame) -target-width)
(set-frame-height (selected-frame) -target-height)
(let ((target-font (if (equal -last-used-font -target-font-1)
-target-font-2
-target-font-1)))
(setq -last-used-font target-font)
(set-frame-font target-font))))
2. Start emacs
$ /usr/bin/emacs24-x -Q -l bug-frame-resize.el
3. Type "M-x bug-frame-resize" four or five times.
The frames appear with the correct size briefly, but then resize after a
split second. On this machine this usually results one of the height or
width is incorrect on each of the created frames.
The bug requires the font to be changed when creating the frame.

(This bug report unfortunately got no response at the time.)
I tried reproducing this in Emacs 28 on Debian/bullseye, but was unable
to. All the Monaco frames have the exact same width/height, and so do
all the Courier frames.
Do you still see this issue in more recent Emacs versions?

The address bounced, so it seems unlikely that we'll make more progress
here, and I'm closing this bug report.
