Steps to reproduce:
In Fedora 32 with Wayland, start Firefox with:
env MOZ_ACCELERATED=1 MOZ_WEBRENDER=1 MOZ_ENABLE_WAYLAND=1 /home/xxx/firefox/firefox %u

It looks like someone else have the issue here: https://www.reddit.com/r/firefox/comments/g5dyfe/why_is_webrender_disabled_in_my_nightly_how_to/
Actual results:
In about:support, I can see:
Composition OpenGL
In about:support Webrender section, we can see:
unavailable by runtime: Failed to render WebRender
With fission enabled, we can see (this how I first notice):
You are running with Fission enabled but without WebRender. This combination is untested, so use at your own risk.
Expected results:
In about:support, I should see:
Composition Webrender

The bug sounds similar to https://bugs.freedesktop.org/show_bug.cgi?id=110872
I suspect https://searchfox.org/mozilla-central/source/gfx/gl/GLContextProviderEGL.cpp#290 maybe being the course here - we shouldn't ask for a compat profile for webrender. I successfully tested an earlier version of D48096 with i965 (which only supports 3.0 with compat profile unlike iris which support compat profile 4.6 on this mashine), and I think that was the difference to the final version. I'm still somewhat confused that the fallback to GLES didn't work :/

Confirmed. My main profile can't even start with gfx.webrender.panic-on-gl-error:true:
