The PoC as output file of my program posted as source code in the previous comment is attached here.

I've removed the attachment to my previous because it was erroneous, I'm sorry. Attached to this post is a corrected and tested version (for creation of a PoC of this issue which I've checked to display correctly with different non-PoDoFo programs). The output PDF will be attached to my next post here. I haven't yet reproduced this issue with it, I don't have the right environment handy right now and need to go on a journey to my new workplace very soon. It might only work on unix-like OSes because...

I'm sorry I only implemented the latter program to produce a PoC PDF with the one-bit-per-pixel PNG as input (for the latter see above, was below when composing this, earlier replies) today and couldn't test it yet, I need to go to bed now as I'll have an important appointment tomorrow early in the morning. The C++ source code of the program is attached here. It takes the PNG file as input on standard input. If you use Windows, please insert a call switching that to binary mode into the source before...

The output PNG file of the program creating a one-bit-per-pixel Paeth-filtered PNG image is attached (it's a QR code of 21x21 pixels).

I'm sorry I didn't attach the program earlier, it's from April 8, 2021. The output file of can only be attached to the next reply.
