Subject: 27.1; toolbar icons
My Linux computers are used only for local development and don't have 
email access. I copied this from the Linux computer (X990) in which the 
problem exists. That I am sending this to you from a Windows computer is 
irrelevant.
--text follows this line--
I have developed a library that includes a toolbar with custom icons. It
works in all versions of Emacs in Windows and in Emacs version 26.3
under Ubuntu-Mate 20.54 but the toolbar doesn't work in Emacs 27.1 under
Ubuntu-Mate 22.04. In my preferred configuration I put my icons under
the user home directory so that this doesn't change if Emacs is
updated. My library accesses this with e.g.
(tool-bar-add-item "~/icons/lxa-next"
to use my lxa-next.xpm icon. In Emacs 26.3 it also works to put my icon
in /usr/share/emacs/26.3/etc/images and refer to it as simply
"lxa-next". Emacs 27.1 shows nothing either way. My lxa-next.xpm appears
similar to the native lock-broken.xpm (4.7kB vs. 4.6kB) so I
experimented referring to that instead of mine and it worked. I also
tested left-arrow but instead of left-arrow.xpm or pbm, it showed a very
plain < image that doesn't exist in the images directory. It should be
noted that there is a lock-broken.pbm but the xpm version was
automatically selected. The icon selection mechanism of Emacs 26.3 is
usable but could be improved by accepting an explicit icon file
extension. That of 27.1 is unusable and, unless we can fix it, I will
have to advise users of my library to install an older version of Emacs.

In GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.33, 
cairo version 1.16.0)
