Glyph out of place, vertically shifted downwards:

Type ;; foo ⟡ bar
where a box ^ displays in place of the WHITE CONCAVE-SIDED DIAMOND
which can by typed by C-x 8 RET white concave-sided diamond RET
but renders as a box instead.

When I start Emacs, with or without init files,
the box is rendered in the correct screen position.

After editing for a while, the box renders on the line below.

		Peace

P.S.  Please find screen shots at http://jovi.net/Emacs-Bug/Render

Any debugging suggestions?

I'm mailing this bug report from a fresh "CLEAN" emacs,
not the long-running bug-manifesting "DIRTY" emacs.

Which font is used here?  Is it the same font in the "good" and the
"bad" display?

And why do you say this is a "new" bug? new as compared to when?

Thanks.

My first suspicion is that this has something to do with your video
driver.

Since you see just a box, it means this font doesn't support that
character.  So I wonder why this font is used for that character.  Did
you try to install Symbola?

New to you because you never saw it before, or new because previous
version(s) didn't have it?

This was a year ago -- Devon, are you still seeing these glitches in
recent Emacs versions?
