Maybe a small thing, but nonetheless irritating: I noticed that when
scrolling buffers on a split frame with disabled scrollbars, the small
line separating two buffers can get corrupted by icons in the fringe. It
seems that this line doesn't get redrawn correctly, or maybe not at all.
You should be able to reproduce this issue with the following recipe:
* emacs -Q
* In the *scratch* buffer, insert
(progn
(scroll-bar-mode -1)
(setq truncate-partial-width-windows nil)
(toggle-truncate-lines -1)
(with-current-buffer (get-buffer-create "test")
(erase-buffer)
(dotimes (i 100)
(insert (make-string 500 65) "\n")))
(pop-to-buffer-same-window "test")
(goto-char (point-max))
(split-window-right)
(other-window 1)
(split-window-right)
(pop-to-buffer-same-window "test")
(goto-char (point-min))
(while (not (eobp))
(scroll-up-command)
(redisplay t)))
and evaluate.
* The separator line between the first and the second buffer should now
have gaps. Here's a screenshot:

As soon as the Emacs window gets redrawn, everything's back to
normal.

It does get redrawn, see x_draw_vertical_border.

Unfortunately, I cannot reproduce this here, neither with stock Emacs
24.2 nor with the current trunk. I get a perfectly drawn border.

I see the issue in emacs-24 and trunk. x86_64 GNU/Linux, Lucid toolkit.

Thank you both for testing. I forgot to add that I've also seen this
under GNU/Linux with the Lucid toolkit, but on two different boxes
(running Ubuntu 12.04 and Arch Linux, resp.). Eli, you've probably
tested this under Windows?

Yes, but it shouldn't matter. This level of redisplay is
device-independent, at least most of it.

Do you see it in previous versions, like 24.2 and 23.3? That will
tell us how urgent it is to fix this.
If this is a regression that needs to be fixed ASAP, can you trace
through the code which draws the border and see what goes wrong there?
The immediate suspects are those parts that reference the
redraw_fringe_bitmaps_p flag, and the x_draw_vertical_window_border
function.
Another possible way to see whodunit is to step through update_window
and update_window_line, and see which code removes the portions of the
vertical line.
Or maybe the problem is in the order in which fringe bitmaps and the
vertical border are drawn.

Since at least 24.1 (recipe does not work as written in 23.x).
I don't think is at all urgent to fix.
I also see it in GTK-2 builds, but it is not as obvious because for some
reason the middle window ends up scrolled to a different position, with
less space after the end of the "A"s.

I agree; this is a purely cosmetic issue and just a bit irritating
(also, it only affects those with disabled scrollbars, which I guess
isn't very common).

Does the change below solve the problem on GNU/Linux and NS?

Thanks for testing.
Glenn, I'd like to install this on the emacs-24 branch, any
objections? The change looks a no-brainer, and obviously correct.
