Hi @Wojciech Sobiesiak,
Everything looks nice when using firefox, when MS edge, my beutiful pdf file is not rendered.
I tested with the PDF content you provided, in Edge, Chrome, Adobe Acrobat they all show a white background, only in Firefox is a black background, I guess this is the rendering problem you mentioned, right?
I tried to make a simple modification in the file (drawing a simple pattern with a brush), save it and open the file again. You'll notice that in Firefox, its background color changes from black to white. You can also see in the print preview that the background color is white instead of black. So I think this rendering is correct in Microsoft Edge.
Based on the above, I'm guessing it might instead be a problem with rendering in Firefox.
Best regards,
Xudong Peng
