I‘ve verified this issue using the latest Firefox Nightly 107.0a1 (Build ID: 20221002212226) on Windows 10 x64, and macOS 12.5.1.

• The background of the images from the “about:welcome” screens is visible on macOS when the “Increase contrast” option is enabled and the Display Contrast is at maximum.

• It seems that the issue is still reproducible on Windows 10 x64, where the background of the images from the “about:welcome” screens is still not visible if the “High Contrast Mode” is enabled.

Considering these, I filed a new issue for Windows OS (Bug 1793401), and I'm marking this one as Verified.

The patch landed in nightly and beta is affected.
:nsauermann, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.
• If no, please set status-firefox106 to wontfix.
