Thanks for checking and confirming.

I think slightly shrinking the image -- either unconditionally or
conditioned on the value of image-height? -- would be fine.  Or, as I
noted earlier, I also get the image if frame-height is 36 instead of the
current default of 35.

Actually, although I reported earlier in this thread that starting the
Emacs that comes with openSUSE 12.1 (23.3) with -q also does not show
the fancy splash screen, I had neglected to remove my .Xresources
setting for Emacs, which specifies DejaVu 10 (which is actually 12pt, as
shown above); when I remove that resource, both openSUSE's Emacs 23.3
and Emacs 24 from the trunk started with -q do show the fancy splash
screen.  This is because the font height is 19 by distribution default.
However, this also results in the final two lines of the splash screen
-- "If an Emacs session crashed recently, type Meta-x recover-session
RET to recover the files you were editing." -- not being visible
initially.  Maybe this sentence should come earlier.
