I don't think it can be the mode line font as the minibuffer frame does not
have one.  But I tried with different minibuffer fonts, and it looks as
though you both are on to something.  I've attached a screenshot with:

[1]  +  9267 Running    src/emacs -Q --font=5x8 --eval  ...
[2]  -  9272 Running    src/emacs -Q --font=6x13 --eval  ...
[3]     9275 Running    src/emacs -Q --font=9x15 --eval  ...
[4]     9282 Running    src/emacs -Q --font=10x20 --eval  ...

You can see that with the 10x20 font, the hanging parts of the letters are
displayed.  The other fonts are not displayed with sufficient space for the
letters.  I'm not sure it is quite correct even with the 10x20 font though -
there is (exactly) enough space for the letters but not enough for the
bottom of the scrollbar nor cursor box.

Note also that all fonts result in extra pixel space to the right of the
fringe.  Where does this come from???

I began to wonder if this is due to my X server, if that is the correct
terminology, which is Hummingbird's Exceed (I have the latest version).  I
use Exceed on my PC to provide the Solaris CDE environment on my PC.  Exceed
is using the Solaris' font server.  I am using a CVS Emacs built on Solaris.
I tried displaying the same Emacs on a GNU/Linux machine (some flavour of
RedHat) which is presumably running some Xfree86 server or something.  On
that display, I do not see a problem with either character space or fringe
space.  So presumably it is related to the information that Emacs is getting
from the Solaris font server via Exceed?  I do not know how to determine
where the problem lies: it may be that Emacs is not dealing with the
information properly.  I do not see any problems with any other applications
I use.

There is an additional problem that may help here.  If I start Emacs with:

src/emacs -Q --geometry=80x20 --font=9x15

Then under Exceed I get an Emacs frame containing a *scratch* buffer whose
window is 78x17 in size as reported by window-width and window-height.  On
the GNU/Linux box, the window is 80x19.

How can I help find what the problem is?

Simon.
