The frame’s size does not change (if you mean the window gets narrower for a
narrower font, say).
The set-frame-width expression doesn’t make any difference when I change from
Monoco to Menlo and back.
Another interesting thing:
* The problem does NOT occur when changing the size of the font.
* If I change the font (to Monaco), the screen blanks, but immediately running
a command to change the font size “fixes” it.
Seems that the font-change isn’t triggering a “repaint the whole thing”,
rather, just repaint the line containing the pointer.
Functions involved in font-size change (really just set-face-attribute):
(defun kfi/set-font-size (size)
"Set the font SIZE."
(interactive "nNew size: ")
(set-face-attribute 'default nil :height size))
(defun kfi/font-size-up ()
"Shift font size up by 10 units."
(kfi/set-font-size (+ (face-attribute 'default :height) 10)))
(defun kfi/font-size-down ()
"Shift font size down by 10 units."
(kfi/set-font-size (- (face-attribute 'default :height) 10)))
