Just for checking: If you change the following two forms

(add-to-list 'default-frame-alist '(left-fringe . 11))
(set-frame-size (selected-frame) 1905 1054 t)

to say

(add-to-list 'default-frame-alist '(left-fringe . 17))
(set-frame-size (selected-frame) 1899 1054 t)

do you still get the same value for the frame pixel width, namely 1920?

I don't understand how these get calculated:

(* 11 174) gets me 1914.  Add 4 pixels for the internal border gets me
1918.  Where do those two pixels missing to 1920 go to or come from?

(* 20 52) gets me 1040.  Add 4 pixels for the internal border gets me
1044.  10 pixels missing to 1054 for what?

Do you have any means to trigger maximization from the window manager
via some sort of maximize button?

BTW, can you run Emacs under GDB?
