And memory leaks, a few are known.  Having talked to Richard Koch,
I know he hed to decide whether to live with some dumb memory
deallocation on the side of PDFkit or accept memory leaks. And
PDF has some bugs that should not be there....

That the API is easy, I know.  That it is hard to circumvent
some peculiarities, is also known.

Interesting. You are the first person I know reporting no problem
with page 22 of that file. It happened to me ONCE that Preview
previewed it without problems, which is a bit weird.
