26.1; display problem with mode-line turned off on terminal |
|

Running Emacs in a terminal and setting mode-line-format to nil can
cause incorrect display of buffer contents.
emacs -Q -nw
M-: (setq mode-line-format nil)
C-x C-f lisp/org/org.el.gz ;for example
RET RET RET... DEL DEL DEL... ;add and delete white-space
Note the second-to-last row in the window, which formerly held the
mode-line, does not display the buffer contents correctly and any buffer
line that moves through the last row (when back-spacing) appears blank
further up the window.
I mainly observe this in emacs-lisp-mode and org-mode. The problem
doesn't seem to occur when:
+ in fundamental-mode, c-mode or text-mode, or
+ visual-line-mode is active, or
+ the frame contains more than one window (v or h split), or
+ avoiding display of each line (e.g. C-u 10 RET C-u 10 DEL).
