Use this /tmp/cant-next-line.el to automate a little more.
(tool-bar-mode 0)
(global-whitespace-mode 1)
(set-face-attribute 'default nil :height 80)
(setq scroll-margin 4)
(setq scroll-conservatively 101)
(add-hook 'emacs-startup-hook (lambda ()
(re-search-forward "here")
(trace-redisplay)
;; Doesn't reproduce it, have to C-n manually
;; (run-at-time "1 sec" 1 (lambda ()
;;
(call-interactively 'next-line)))
))
Reproduction won't happen if you:
- resize the window
- use M-x next-line instead of C-n
- press and hold C-n
- navigate in ways other than prescribed
I can see it everytime I follow the recipe.
Here is the trace-redisplay resulting from:
./src/emacs -r -Q --load /tmp/cant-next-line.el /tmp/cant-next-line.txt
Then C-n 5 times
