Zotero PDF viewer is blurry at high zoom levels [7.0.0-beta.25+8a7f3645b (64-bit) / Win11]

Hey everyone!

I often take screenshots of illustrations from textbooks. If I zoom in closely, my PDFs look blurry and the text isn't sharpened like in Adobe Acrobat. Here is a side by side comparison using the same PDF file. https://imgur.com/a/PrHUfaq

Is there an option I can tweak to change this?

Thanks in advance!

    Can you email the PDF to support@zotero.org with a link to this thread?

    Unfortunately, this is a limitation of the Zotero PDF reader, which is based on PDF.js. If you zoom in too much, it has to reduce resolution.

    Does it mean that the new PDF reader cannot display sharp vectorial contents at high zoom level, including text and images? This sounds like a serious drawback compared to external PDF viewers like Acrobat.

    It's the same as in Firefox browser.
