I suggest to focus on finding a way to switch between Emacs 24.5 and
25.1 without hitting this problem.  Assuming we find a good way of
doing that, adding that to NEWS should allow people to avoid the
problem you bumped into.

I proposed to solve this by including this single line in your
~/.emacs:

  (modify-all-frames-parameters '((horizontal-scroll-bars . nil)))

If you do that, and then start Emacs 24.5 and save desktop, does the
problem disappear after restoring the desktop in Emacs 25.1?
