  1. Resolution Note (fix version 2022.2):

    Fixed in: 2021.3.4f1, 2022.2.0a11 and above.

    The problem only appears when using linear colorspace. Alpha support had been disabled because of browser bugs in handling linearization of sRGBA content. The disabling has been restricted only to the browser platforms where this is known to be broken, which is Firefox and WebKit-based browsers. Chromium-based browsers are now back to supporting transparent videos in linear colorspace. Note that transparent videos in sRGBA colorspace are not impacted by this (they were and remain functional).
