PNG images with a transparent background are not transparent.
Look at the image emacs_png_bug.png on the attachment.
This is my first bug report. If I am missing something please let me know.
Below are the commands i used to compile the emacs.
git clone https://github.com/emacs-mirror/emacs.git
*cd emacs*
*./autogen.sh*
*./configure*
*./configure --with-mailutils && makemake install*

Well, does anyone want to fix this?
It should be "as simple" as making libpng use the same code in
x_query_frame_color to allocate transparent colors. But I have no idea
how to make libpng do that.
In the meantime, you can use XPM images for that icon instead, which are
free from this problem.
