PDF.js Express Version
8.7.0
Detailed description of issue
Hello, some pdf generated by tesseract ocr are not rendering properly on PDFjs express.
The problem is probably due to the version of pdfjs used by PDFjs express. This problem also exist in pdfjs 2.15 but is fixed using one the latest version ( tested on 3.3.78 ).
test_page1.pdf (131.0 KB)
Expected behaviour
PDF should render all pages without issues.
I just tested this document on the PDFjs Express demo site and I think it was rendered correctly. Could you confirm this?

Hi @zserviss, I tested on my side, but it wasn’t rendered properly, at least on firefox.
But it’s partially rendered on google chrome ( the first few number are rendered properly, but not the digital signature which is missing its text ).
Interesting, I’m able to render correct on Safari, Chrome and FireFox.
I am on an M1 MacBook, what devices are you seeing this on?

@zserviss I am on a windows 11 using Citrix virtual desktop. I’ve tried on my host machine ( standard Lenovo ), with the same results.
It may be related to the font provided by the computer ( checking off [ browser.display.use_document_fonts ] in about:config on firefox will show the text, but will disable all other fonts ).
Could you try to disable the hardware acceleration on browsers to see if that fixes the issue?

Could you please attach your computers specs?
