Steps to reproduce:
1. $ emacs -Q -D &
2. M-x scroll-bar-mode RET
3. M-x scroll-bar-mode RET
Then you'll see a blank column to the right of the scroll bar.

Does the frame shrink after step 2 and expand after step 3? Does the
blank column appear below the tool-/menubar or at the right of its end?
I suppose everything happens within ns_set_vertical_scroll_bar. So to
investigate this further, could you please step through this function in
order to find out what's different between when Emacs displays the
scrollbar for the first time and when it executes step 3. In particular
the respective values of `left' after
left = WINDOW_SCROLL_BAR_AREA_X (window);
would be interesting.

On MS-Windows, step 1 produces a frame with no scroll bar, but Emacs
evidently thinks the scroll bar is still there, because step 2 says
"Scroll-Bar mode disabled". Repeating step 2 after that, followed by
step 3 produces correct display.

The original report said Gtk+ so I guess not...

I think it is something wrong with -D. Emacs starts with no scroll bars, but when you do the first M-x scroll-bar-mode, Emacs says "Scroll-Bar mode disabled".
Without -D this works fine.
It also works fine with NS or no toolkit. Lucid gets the extra column on the right, but the scroll bar appears on the left.

Hopefully fixed now. Please try again.

Emacs still thinks the scroll bars are displayed when it is started
with -D: step 2 says "Scroll-Bar mode disabled", although the scroll
bar was not shown before that.

That's a different issue. I only fixed the blank column part (which I
couldn't even observe on Windows).
I don't know how -D is processed internally and what its semantics wrt
scrollbars should be. What's probably needed is to either disable
scroll-bar-mode or reset the `vertical-scroll-bar' parameter of the
initial frame.

Ah, OK, I thought it was related.

Right, I don't see it as well.
Sorry for the noise, I saw Jan saying that -D behaves the same on GTK,
so I thought these are symptoms of the same problem.

Fixed for me. Thanks. It has also fixed another bug I was about to
report (The right part of (non-toolkit) toolbar is not drawn with
similar scroll bar configuration change even when we started without
-D).
Closing.
