It didn't happen when I just executed the code manually in *scratch*, but
it does happen for me if I save Edward's instructions in a file xx.el,
and run emacs like this:
emacs -Q -D -l xx.el
---- xx.el:
;; Step 0: Launch an Emacs on some variety of window-system.
;; Step 1: Ensure that there's something in the mode-line that changes
;; periodically.
(defvar frob " hello")
(add-to-list 'minor-mode-alist '(t frob))
(defun frob-it ()
"Change `frob' to a random string, and force a mode-line update."
(setq frob (concat " " (make-string (+ 2 (random 6))
(+ 97 (random 26)))))
(force-mode-line-update t))
(run-with-timer 5 5 'frob-it)
;; Step 2: Ensure that there's a buffer with no mode-line.
(with-current-buffer (get-buffer "*scratch*")
(setq header-line-format mode-line-format
mode-line-format nil))
;; Step 3: Make a key binding for switching between the buffer with no
;; mode-line and a buffer with a mode-line which uses
;; `switch-to-buffer'.
(global-set-key (kbd "C-c c")
(lambda ()
(interactive)
(if (eq (current-buffer) (get-buffer "*Messages*"))
(switch-to-buffer (get-buffer "*scratch*"))
(switch-to-buffer (get-buffer "*Messages*")))))
;; Step 4: To observe the bug, switch to *scratch*, wait for the
;; header-line to change, and hit C-c c. More often than not,
;; the mode-line in *Messages* will be only partially
;; displayed. (Try this several times, by repeated use of the
;; C-c c key binding, if you don't observe the effect right
;; away.) Typing C-l (unsurprisingly) fixes the display.
