Subject: 24.0.50 and 23.2.*; Cursor disappears over embedded images in recent
	--with-ns emacs
Date: Mon, 15 Nov 2010 20:21:21 -0500

[Message part 1 (text/plain, inline)]

In recent emacs (23.* and 24.0) on Mac OS X snow leopard, built using
"./configure --with-ns", the text cursor disappears when it is over
embedded images.

To reproduce the problem, substitute a path to the frown.xpm on your
system in the following and evaluate it:

(insert-image
  (create-image
"/usr/local/share/emacs/23.1.90/etc/images/smilies/frown.xpm"
  'xpm))

Then move the cursor over the resulting frown smilie, and all traces of
the cursor will disappear.  The cursor will reappear if you move it off
of the frownie.

This problem occurs whatever shape I assign to cursor-type.

I've experienced this problem with checkouts built from the trunk as of
today (Nov 15, 2010) and the tag EMACS_23_2, and i also see it when
using the "Emacs for OS X Modified" downloaded from
http://vgoulet.act.ulaval.ca/en/ressources/emacs/mac (23.2.50).

Perhaps a related problem: setting the foreground color of the cursor
with 'customize-face cursor' face has no effect - the foreground color
of text under the cursor is always the same as the text when it is not
covered by the cursor.  Setting the background color does what it is
supposed to do.

the cursor-disappearing-over-embedded-graphics problem does *not* happen in
the version of emacs built with the emacs-mac patches found at

ftp://ftp.math.s.chiba-u.ac.jp/emacs/emacs-23.2.90-mac-1.998.tar.gz


this is the only mac-native build of emacs 23 or later i've tried that
doesn't have the problem.

Sorry it's taken so long for someone to respond. I can't reproduce this
in Emacs 25. Can you confirm whether it's still a problem?

Thanks!

I see an outline of the cursor box, using the cursor color, when it's over
an image in Emacs 25, and Emacs 24.5 for that matter, so I think it's ok.
