On Emacs Windows


It seems like the observation of
https://lists.libreplanet.org/archive/html/help-gnu-emacs/2023-11/msg00109.html
has never been reported as a bug.

This issue is real. When I spilt a Windows with C-x 3 and save the desktop
and re-open the desktop, the scrollbar separating the two windows is
broader than it used to be before saving.

When I manually open the .emacs.desktop file and delete the setq
scroll-bar-width and reload the desktop, the width is back to normal.

Because, as I responded there, I couldn't reproduce the problem.

I still cannot reproduce this.  maybe this has something to do with
the display settings?  Like HiDPI, perhaps?

What is the value of scroll-bar-width recorded in the desktop file,
and what does the below yield if you type it after "C-x 3" before
saving desktop?

  M-: (frame-parameter nil 'scroll-bar-width) RET

Adding Cecilio, in case he has an idea why this could happen, or can
suggest a way to debug this.
