Re: GM loses transparency on some grayscale PNG images?

No problem, I just heard back from my contact at Automattic, originally
they said it was fixed in newer versions, but then they said:
I continued investigating... It’s not the GM version that affects this, but
the build flags. If I remember correctly using --with-quantum-depth=16
would fix it for some cases, but not all.
https://code.trac.wordpress.org/changeset/488/ should be a universal
workaround.

Going to see if they have any examples of what/how it was broken though.
