WebGL stopped working in Firefox

[tad-lispy]

I've just updated my NixOS and WebGL stopped working in Firefox. It still works in Chromium. Previous generation, where it works is 5 days old. The version of Firefox is the same (109.0.1 (64-bit)).

For example, this page http://webglsamples.org/aquarium/aquarium.html displays this to me:

It does not appear your computer supports WebGL.

Click here for more information.

Status: WebGL creation failed: WebglAllowWindowsNativeGl:false restricts context creation on this system. () Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)

and a bunch of warnings in the console:

WebGL warning: <Create>: WebglAllowWindowsNativeGl:false restricts context creation on this system. webgl.js:159:24
Failed to create WebGL context: WebGL creation failed: 
* WebglAllowWindowsNativeGl:false restricts context creation on this system. ()

Failed to create WebGL context: WebGL creation failed:

* Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)

And my own project at https://tad-lispy.gitlab.io/bevy-lion-playground/ gives following errors:

Here's a diff of a dump from about:support in Firefox on working vs broken generation:

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

Is this still a problem?

Is this still a problem?

For me yes.. On mesa-amber driver i got the same result on firefox 112 and for glxgears

ATTENTION: default value of option vblank_mode overridden by environment.
intel_do_flush_locked failed: Invalid argument```

glxinfo | grep "OpenGL version"

For me it eventually got fixed after some updates. Probably with a new kernel version. I'm sorry I can't provide any more details. Good luck @MadDogMayCry0 !

I'm having a similar issue. I'm using nix (not on nixos). The firefox version of the system supports webgl, but the one installed with nix doesn't

[kindsun]

Is this an issue that just needs someone to step up and tackle or is the current group maintaining the package genuinely stumped on the problem? I only ask because this is something that affects me daily running Nix on stock Ubuntu. I really love Nix and hate to see my setup fail on something so important to daily operations as Firefox. So if this needs a champion, I'll start looking into it!

[mweinelt]

If WebGL isn't working it likely isn't able to find your graphics drivers. I'm personally only use NixOS, so I can't reproduce.

[mweinelt]

Can we first make sure, that libva can find your driver?

nix shell nixpkgs#libva-utils -c vainfo

Then check the following issue for how to get some logs from Firefox wrt driver selection through the use of VAAPI hardware decoding of videos.

https://github.com/NixOS/nixpkgs/issues/157061

[plaflamme]

In my case:

❯ nix shell 'nixpkgs#libva-utils' -c vainfo
Trying display: wayland
Trying display: x11
libva info: VA-API version 1.20.0
libva error: vaGetDriverNames() failed with unknown libva error
vaInitialize failed with error code -1 (unknown libva error),exit

So, presumably, this means that libva isn't finding my driver.

As for firefox logs, I'm not sure what I'm looking for, but I can see this at the very top:

❯ MOZ_LOG="PlatformDecoderModule:5" firefox
[GFX1-]: glxtest: libEGL no displayERROR
...

Other lines seem mostly related to audio.

[mweinelt]

See https://github.com/NixOS/nixpkgs/issues/272269#issuecomment-1841048492 if you are not on NixOS.

[kindsun]

See #272269 (comment) if you are not on NixOS.

This ended up being the solution for me. Specifically using NixGL as mentioned a little further down in this comment. What I ended up with isn't quite as seamless or repeatable as I'd like, but the other issue seems more focused around this.

[mweinelt]

Thanks for the feedback. I'll close here, as this issue has served its purpose twice over after mixing various environments with different root causes.

Set hardware.opengl.enable = true; on NixOS.
