Imported PDFs are blurry despite being vector based

[JaxTheWolf]

Describe the bug

I have recently started to migrate from Notein to Saber, with all my notes as well. After importing into Saber the PDFs are blurry, whereas in any other PDF viewer on my device they remain sharp upon zooming.

To reproduce

1. Import any PDF with vector based graphics (Even exports from word processing apps exhibit this issue)
2. After importing is done, zoom in.
3. Compare to zooming in in any other PDF viewer

Expected behavior

The PDFs should render using actual vectors, not being rasterized. I know this can be an issue with large files, but it could be mitigated using a lazy loading system, where only the visible parts are loaded and the rest is only properly loaded upon the user scrolling to them.

Saber version

v1.29.1 (129010)

Device

• Device: Desktop
• OS: NixOS unstable
  Same issue appears on my phone and tablet

Anything else?
