I don't know for sure, but I'd bet that it is similar to Qwertuoso: https://www.linusakesson.net/software/qwertuoso/underworld.p...

Thanks for posting that link. :)

If that is indeed the case, we'd appreciate a bug report over at https://bugs.ghostscript.com It is hard to fix issues we don't know about. :)

Do you mind reporting those issues either to SumatraPDF at https://github.com/sumatrapdfreader/sumatrapdf/issues or directly to MuPDF at https://bugs.ghostscript.com/ if it also has the same issue? Thank you!

There are many wonderfully weird PDFs and epubs out there, but we do our best to fix issues. :)

Usagi Electric has a video series[1] about investigating MC14500B (with help from Ken) and recreating it on a bread board. Later this led to him developing a variation on MC14500B using vacuum tubes[2].

Do you mind reporting this over at https://bugs.ghostscript.com/ ? I work on MuPDF myself, but I'm sure my colleagues working on Ghostscript would want to have any differences fixed. Thank you! :)

You can also reach us developers over at our ghostscript Discord channel https://discord.gg/H9GXKwyPvY (https://discord.gg/SnXWzqzjKs for mupdf).
