1949930 - Most games on itch.io show a black window with RFP enabled

Status: RESOLVED DUPLICATE of bug 1684230

(Core :: Privacy: Anti-Tracking, defect, P3)

Description

[sworddragon2]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:135.0) Gecko/20100101 Firefox/135.0

Steps to reproduce:

1. Set privacy.resistFingerprinting to true.
2. Go to itch.io (for example into this category: https://itch.io/games/free/platform-web/tag-idle ).
3. Try to start some games listed there within the browser (for example https://barribob.itch.io/tower-wizard ).

Actual results:

When the game has loaded the site/window just stays black.

Expected results:

The game should display normally.

Additional details:

In the past months I noticed that around half of the idle games here break but now this drastically increased and also affects now games that previously worked. In the past sometimes the game also started rendering/changing to black when altering the window size (since I also use privacy.resistFingerprinting.letterboxing=true and many games open in popups).
