This pdf is always rendering correct in the above cases:
[^working_pdf_with_signatures.pdf]
This pdf is signed with PDFBox and used for the screenshots:
[^not_working_pdf_with_signatures.pdf]
Note that the Preview issue might be a different one but as the other file also

It looks like this is related the Preview issue:
[http://www.openradar.me/34276970] (in which case it also might be related to
this issue somehow).
