Cannot maximize Emacs frame on MacOS; 10pixels missing at the bottom

I am using Emacs 28.1 on a Mac:

    (emacs-version)
    "GNU Emacs 28.1 (build 1, x86_64-apple-darwin21.4.0, NS
appkit-2113.40 Version 12.3.1 (Build 21E258))
     of 2022-04-20"

After updating MacOS to Monterey v. 12.4 two days ago, I cannot
maximize the Emacs frame anymore. At the bottom of my frame are
10pixels missing. See attached screenshot.

Here are my frame settings:

    ;; center frame 2/3 of the screen size
    (progn
      (setq initial-frame-alist '((top . 25)
                                  (left . 426)
                                  (width . 241)
                                  (height . 100)))
      (setq default-frame-alist '((top . 25)
                                  (left . 426)
                                  (width . 241)
                                  (height . 110)))
      (add-to-list 'default-frame-alist (cons 'vertical-scroll-bars
nil)))

Here are my monitor-attributes and frame parameters:

    (display-monitor-attributes-list)
    (((geometry 0 0 2560 1440) (workarea 0 25 2560 1415) (mm-size 596
335) (frames #<frame *scratch* 0x7fb0dc8b8430> #<frame workspace:
PLANNER 0x7fb0e28bf7b0> #<frame workspace: Emacs Lisp 0x7fb0e44d4e00>)
(source . "NS")))



    (frame-parameters)
    ((tool-bar-position . top) (parent-id) (explicit-name . t)
(display . "pragmat1c1s-MBP") (visibility . t) (icon-name) (window-id
. "3") (top . 25) (left . 1280) (buried-buffer-list #<buffer
*Backtrace*> #<buffer TAGS>) (buffer-list #<buffer *scratch*> #<buffer
*Minibuf-1*> #<buffer init.el> #<buffer *Help*> #<buffer *Org
Agenda*>) (unsplittable) ...)

Not sure if that would help in your case, but you might wanna try
setting:

    (setq frame-resize-pixelwise t)

Wow, that did the trick! Thank you very much!

What was I doing wrong?

I think it would be best to refer to the [manual](https://www.gnu.org/
software/emacs/manual/html_node/elisp/Frame-Size.html#index-
frame_002dresize_002dpixelwise):

> If this option is nil (the default), a frame’s text pixel size is
usually rounded to a multiple of the current values of that frame’s
frame-char-height and frame-char-width whenever the frame is resized.
If this is non-nil, no rounding occurs, hence frame sizes can
increase/decrease by one pixel.

Now I get it: After your comment and this post here \[1\] I realized I
wasn't dealing with pixels but frame-char-height/-width. And I was
wondering all the time what the unit of my width/height numbers was.

FYI, I solved this by carefully covering the bottom 10 pixels of my
screen with duct tape. Works great so far.

Wow, this is a great customize option that I've been wanting my whole
life but never realized existed.
