Steps to reproduce:

Upgraded to Firefox 83 on Ubuntu 20.10 on Wayland.


Actual results:

When I try to launch a webGL game:
Failed to create WebGL context: failIfMajorPerformanceCaveat: Compositor is not hardware-accelerated.

Specifically Pixi says:
Error: WebGL unsupported in this browser, use "pixi.js-legacy" for fallback canvas2d support.


Expected results:

The game should have launched. There is no reason WebGL should fail.

Downgrading to FIrefox 82 works, but is not workable. It forces me to
create a new profile, so I lose everything I've built up over the last
18 years.

Managed to restore functionality with --allow-downgrade. But this is
obviously not a long-term solution.

Per Ubuntu developers' suggestion, I tried the upstream build of Firefox
(83.0.2), and it behaves the same way. That suggests this is an issue in
Firefox and not Ubuntu's build and packaging.
