FWIW, also had a related issue today. Read a monthly invoice, and the document itself is fine, and some of the variable content is in a different font.
It really looks ugly and pixelated, partially barely readable. And the last invoice ~30 days ago looked perfectly fine, so something in between must have caused this regression.
Using a different viewer like e.g. evince also works just fine, document looks as expected and fonts are all perfectly fine.

That doesn't make much sense for us, as outdated or not, poppler did work just fine for us until this issue showed up.
