On Mobile (using Mull) the PDFs are completely pixelated and simply dont render more details. Even after zooming in it takes forever.
Meanwhile on Desktop (Librewolf, Firefox, … on Fedora) it seems a bit slow compared to Okular, but it is very fine.
Strange…
I have NoScript and UBlockOrigin installed, disabling both didnt change anything.
Disabling both and enabling JIT didnt change anything. Maybe it is a GrapheneOS issue?
I dont know, I have ublock, but not using the rest
