We should investigate this off-by-one issue separately.

In any case, what does evaluating (frame-geometry) return for the five
cases:

(1) emacs -Q

(2) emacs -Q -iconic

(3) emacs with your .emacs

(4) emacs -iconic with your .emacs

(5) emacs -iconic with your .emacs for the new frame after C-x 5 2

Maybe you could also try replacing ‘default-frame-alist’ with
‘initial-frame-alist’ but I doubt that would change anything.

I suppose so.  I tried with your ‘default-frame-alist’ settings in
.emacs on Windows and can reproduce it with versions up from Emacs 21.
So apparently this never worked here.  Do you incidentally have an older
version of Emacs where this works correctly?  Which OS and window
manager do you use?

Thanks, martin
