Any difference when using the Pdtron player and the PDFJS express player?

Which product are you using?
PDF.js Express Plus and pdfTron (trial for now)

PDF.js Express Version
6.3.4

PDFTron Version
8.12.0

Detailed description of issue
I have a ppt file that was converted using cloudconvert as a tool to convert office-based files to pdf files so that I can preview in the web, problem is that on the provided file down below, the pages is showing missing parts when using PDFjs express + while it renders completely fine when using the PDFTron viewer.
Is there anyway, or any parameter I can use to properly view the file ?

Expected behaviour

Code snippet
I used the examples provided in the public repos on github and simply changed the path to the file.

Thank u for your time :slight_smile:

Hi there,

Thank you for reaching out to pdf.js express forums,

It seems like pdf.js express viewer seems to have issues loading that particular color. Were you able to reproduce this issue with that particular gradient?
Is the issue reproducible if you convert via a different converter?

Thank you in advance.

Best regards,
