A bit more information:

This is on a tty (urxvt). The problem only shows up when the
problematic window is not selected.


I managed to come up with other weird behavior related to the
redisplay changes:


1) Shell buffer delayed update

In a *shell* buffer, do:

while sleep 1 ; do echo Fnord ; echo Frob ; done

This will redisplay about 6 lines at once, instead of two at once
Remember to have a different window selected.


2) Gnus startup weirdness

Do

(global-set-key (kbd "C-z")
  (lambda ()
    (interactive)
    (message "Fnord!")))

and hit C-z while Gnus is starting up. At least for me, messages
in the minibuffer will cause the group display to be messed up,
mostly by keeping the gnu logo displayed. This fixes itself after
a short time.


All of this is fixed by selecting the problematic window.
