Subject: bug#34710: the mode line flicks on set-window-vscroll
Date: Sat, 2 Mar 2019 19:25:13 +0900 [thread overview]
Message-ID: <3D005746-B3FB-4915-A406-10DD0935C671@misasa.okayama-u.ac.jp> (raw)
On Emacs-26.1.92 build for macOS, I see the mode line flicks when I
scroll-up using pixel-scroll-mode and mouse wheel. 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?
