1873345 - PDF Viewer: text with a background is invisible

Status: NEW

(Firefox :: PDF Viewer, defect, P3)

Description

[Vincent Lefevre]

Attachment: unredable.pdf

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:121.0) Gecko/20100101 Firefox/121.0

Steps to reproduce:

Open the attached PDF file and display it in Firefox. Note: this is the out.pdf file from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=731164#5

Actual results:

The text with the orange background is not visible (but it can be copied).

Expected results:

This text should be visible, just like with the current poppler-based PDF viewers. Note that old poppler-based PDF viewers had the same issue as Firefox, but it appears that poppler has been fixed (more details in the Debian bug report).

Correction: zathura and Atril still have the same issue as Firefox, but xpdf now makes the text visible.

I was able to reproduce the issue on Win11x64 using Firefox build 121.0 and 122.0b9. After opening the pdf attached text with Orange is not visible on FF only on Chrome.

The graphic objects representing the orange highlights have a blend mode set to Multiply but we don't use it.
