We do not do pdf rendering ourself, poppler does, you can go and file a bug at
https://poppler.freedesktop.org/ but let me tell you this is 99% unfixable
because it's not really a bug, those PDF files are scanned images, and contain
LOTS OF NOISE, see a zoomed section here https://i.imgur.com/UaKtRx2.png When
less zoomed the rendering engine has to decide what to do with all those
"random" dots, and well it seems some engines do something you like better and
some something you like worse.

As an example try firefox, at least here at 100% it's acceptable
