2 weeks ago I don't see black boxes. I've tried with the current showcase on https://pdfviewer.net, on my developer preview, in Mozilla's showcase (https://mozilla.github.io/pdf.js/web/viewer.html), in native Chrome, in Firefox, in Safari, and in Apple's preview app. All of these programs render the bottom of page 12 correctly. However, there are many missing images, and that's also happening in each of these programs. What's wrong with the document?
As for you issue: maybe it's a Windows issue?
Example of a missing image (figure 15):

2 weeks ago Please check if the error also happens on https://mozilla.github.io/pdf.js/web/viewer.html. If so, it's a bug of the pdf.js library, and you'll want to report it over there.

2 weeks ago Odd... Here is a complete breakdown or what I tested.
While I didn't test all possible permutations; the only consistant variables that produce this issue are:
The work around for my app is to roll back to v20.2.0.
Edit: Also tested stable and bleeding edge. Also no difference.

Possible issue in pdfjs 4.3?

2 weeks ago Update Again!!
I am seeing it on the public version of https://pdfviewer.net/ in Firefox when toggled to bleeding edge (pdfjs v4.3.620).

2 weeks ago Hm. I can reproduce your issue in Firefox, no matter which version of pdf.js I'm using. There are no error messages, no file accesses, no exceptions, just nothing. I'm clueless.

2 weeks ago This is closest I've found to a similar issue against pdfjs: https://github.com/mozilla/pdf.js/issues/16287
Since this only an issue (for me) on the -alpha versions I'm ok to close it for now. I'll reopen if I see it in a stable version.
Thanks for looking.

2 weeks ago Well, I'd like to publish the final version soon. I'm afraid it might be a merge that went wrong, but if it is, I'll never find it. I'm not familiar with the rendering engine of pdf.js. Maybe someone else can help?

2 weeks ago Will bleeding edge be 4.4 when you publish?
Do you see any difference between stable and bleeding edge with the PDF attached here: https://github.com/mozilla/pdf.js/issues/16287 ?
This is the same instance (https://pdfviewer.net/extended), same browser (Firefox 126.0.1), same PDF (test.pdf). Only diffrence is stable vs bleeding edge.

2 weeks ago Yes, I'd like to publish the final version soon - basically I only have to run a comprehensive test, but at the moment, so many new tickets come in I always forget to run my test. Even so, it should be a matter of days of weeks, and I suppose that means that the stable branch is still 4.3 and 4.4 is the bleeding-edge branch.

2 weeks ago When you have a 4.4 bleeding-edge version I'll be glad to test it.

2 weeks ago One more data-point then I'll give it rest for today.
I cloned pdfjs and tested my PDF using the webviewer on both master and v4.3.136. Saw no issues in either case.

1 day ago In the meantime, version 20.5.2 has landed. Any news from your side?
Possible PDF rendering issue in v20.5.0-alpha.X:
I've been trying to debug an issue I'm seeing rendering a particular PDF (sorry can't share just yet).
When rendered in my app using 20.5.0-alpha.2 (also alpha.0) I'm seeing tables rendered as black boxes in Firefox (and only Firefox):
The black boxes are part of the canvas rendering; not the text layer.
Rendering the same PDF locally using v20.2.0 or the showcase (pdfviewer.net) does not render like that.
I don't see this in any other browser (tested Chome, Safari, Edge and Brave) but is consistant for Firefox accross OSs (tested Mac, Windows and Ubuntu). Any ideas? I'll work on getting a reproducible PDF that I can share.
