• Operating system and its version: Microsoft Windows 10 v1607
• PDF.js version: 1.5.452

Steps to reproduce the problem:

1. Open attached PDF in latest public demo of PDF.js

What is the expected behavior?

What went wrong?

I should probably add that my Acrobat is not able to correctly render the PDF either, so it may be a case of the PDF document simply being too mangled to fix (or maybe a missing font).

The sanitizer warnings are gone, but the rendering problems remain unfortunately.

Did this issue get resolved in the recent versions of pdf.js?

It's not yet fixed, in fact, it looks much worse for me on Linux/Firefox than on the screenshots above (see my screenshot below), but with largely the same (perhaps a bit more specific) sanitizer errors:
