Emacs: 26.0.90
OS: debian 8.0 x86_64
1. start emacs with -Q arg
2. eval the followng lisp code:
(progn
(set-frame-font "Monospace:size=18")
(set-face-attribute 'mode-line nil :font "Monospace:size=18" :height 0.9)
(setq scroll-margin 2
scroll-conservatively 0)
(setq-default header-line-format mode-line-format))
3. open a test file with lines more than window-height
4. go to end of buffer
5. eval this line: (scroll-down 100)
6. Now the margin seems not be 2. If I press M-x, emacs scrolls.
PS: The next-line command doesn’t trigger the problem.

I cannot reproduce this. Can you explain in more detail what you mean
by "the margin seems not be 2"? Maybe I didn't understand what you
saw.

I've succeeded in reproducing this and fixed it on the emacs-26
branch.
Thanks.
