What version are you running? The new one (version 2 onward) or the legacy dir project?

I can't find any resource online about this error pertaining to a specific PHP code snippet, Can you please check your libpng version?

Thanks, there was that one issue that was supposed to be solved in libpng 1.5.something, but you already are at version 1.6.

I've got nothing. 🤷‍♂️

I can confirm this warring that's clogging up my log too. I'm on libpng 1.6.28 version.

I'm looking at the discussions here: https://sourceforge.net/p/libpng/bugs/237/
the warning might actually relate to PHP.

Yeah, I feel like we've been doing image manipulation wrong for a while.
