I think there's a problem with the alpha channel with certain
PyMOL images, which means that portions end up being transparent when
they shouldn't be. A quick workaround is to put a black rectangle
behind the PyMOL image, but I'd like to get a little more information
about when the problem occurs so that we can generate a permanent
1) Does it happen with ray-traced images, OpenGL images, or both?
2) Does is only happen with transparent surfaces?
3) Does it only happen on selected platforms?
And if possible, can you send me directly (not to the mailing list), a
copy of the problematic PNG file.
