Subject: bug#5463: Fringe / scroll-bar weirdness and redisplay troubles
Date: Mon, 30 Dec 2013 10:38:14 +0100

> Some problems with fringe width, and also frame redisplay after moving
> the scrollbars. This happens on Windows, with "GNU Emacs 23.1.91.1
> (i386-mingw-nt6.1.7600) of 2010-01-24 on ODIEONE".
> 
> In the following captures, I've used
> 
>    emacs -Q --eval "(set-face-background 'fringe \"gray60\")"
> 
> to make the fringe more visible.
> 
> Problems:
> 
>  - Right at the start, the fringes aren't the same width (see
> bug1.png). However, (window-fringes) => (8 8 nil)
> 
>  - After "Options / Show-Hide / Scroll-bar / On the Left", I see
> bug2.png. The scroll bar has moved, and the fringes have switched
> width.
> 
>  - Now, after "Options / Show-Hide / Scroll-bar / On the Right", I see
> bug3.png. You can see the left side has not been properly drawn. In
> fact, if I put the cursor somewhere in the buffer, Emacs redraws the
> character that is really underneath (that's what causes the weird
> "ownfbuf er" in the buffer's text).

Can you still see this?
