The mode line does not flick on scrolling-down. I do not see this problem in Emacs-26.1.92 build for Windows. macOS$ /Downloads/emacs-26.1.92/nextstep/Emacs.app/Contents/MacOS/Emacs -Q M-x pixel-scroll-mode M-: (pixel-scroll-up 1) ; => the mode line flicks M-: (pixel-scroll-down 1) ;=> no flick I narrow down the problem and notice that following two blocks response differently. #+begin_src emacs-lisp (dolist (vs (number-sequence 1 10)) (set-window-vscroll nil vs t) (sit-for 0)) ;; the mode line flicks #+end_src #+begin_src emacs-lisp (dolist (vs (number-sequence 1 10)) (set-window-vscroll nil vs t)) ;; no flick #+end_src Do you have idea?
