I built Emacs 25.3 from source, and it behaves the same for me as Emacs 26 (no scrollbar appears). I don't know why the bundled emacs25 behaved differently. Maybe different configuration options, or Debian-specific patches? But at this point I have enough other things on my to-do list that I'd rather not spend more time trying to track it down. best regards, mike
