Configuration:

• Web browser and its version: Firefox 79.0 (64-bit)
• Operating system and its version: Linux Ubuntu 18.04 up-to-date on this date
• PDF.js version: I don't know how to check it...
• Is a browser extension: no

Steps to reproduce the problem:

1. open the attached file in Firefox
2. open with other viewers and chrome

What is the expected/wrong behavior?

There is a line join which is drawn differently in PDF.js:

Coincidentally this exact case was also reported in another issue that got fixed recently. I can't seem to find that issue right now, but if you open the file with https://mozilla.github.io/pdf.js/web/viewer.html it's correct now in the latest master version.

I suppose is #12010... Didn't find it before, sorry. Same file and same problem. If you should need it, I can try to generate an uncompressed minimal PDF.

Thanks anyway!

Yes, that's the one. The patch in https://github.com/mozilla/pdf.js/pull/12044/files contains a reduced test case, so I think it's all taken care of. Thank you!
