Status: RESOLVED DUPLICATE of bug 1778068

(Firefox :: PDF Viewer, defect)

Description

[jscher2000]

Attachment: Example from SUMO

Steps to reproduce the problem:

1. In Settings > Manage Colors..., uncheck "Use system colors" (browser.display.use_system_colors => false) and change the Background color (browser.display.background_color) away from #FFFFFF to any other color

2. Load or refresh the sample PDF. In addition to the page background color changing, the color of the blue, red-orange, and maroon lines changes to black while the color of the yellow line becomes transparent

Users reported this started with the release of Firefox 102. For example:

Vector/Line drawing colors should not be modified by a custom background color.
