I just upgraded Firefox to 84.0 on F33, and the changelog on GNOME Software said “WebRender enabled by default on Wayland and GNOME Xorg”. This is my case here (Wayland with Nouveau on a good old Nvidia GTX 750 Ti). However, “Compositing” is set to “Basic”, and WEBRENDER_QUALIFIED appears as
"denied by env: Not on allowlist". Below follows some snippets from
Graphics -------- Features Compositing: Basic ...

So, is this expected behavior, or is there any chance my card is wrongly blacklisted?
