To be safe, we should keep using ANGLE for webgl1. WebGL 2 is where we actually want this anyway.

We also need to require DXGL interop as a prereq for using WGL.

This will only run if they receive a WGL context, and we have a blocklist
entry for this. Since there isn't a reason right now to want WGL without
DXGL, we should tie these together.

What's the justification for allowing WGL without DXGLInterop2? It seems to me like ANGLE would be a better option in that case.

We're blocking ANGLE on WebGL 2 for now because it doesn't work yet, and WGL is disabled for WebGL 1, so these are currently mutually exclusive.

We can do more sophisticated fallbacks as WebGL2+ANGLE comes online.

I thought part of the rationale for using ANGLE was that we didn't trust drivers to deal with untrusted inputs because of the security risk.  Is that not the case anymore?  Is there something else that prevents untrusted input from Web content from going straight to the driver, or do we actually believe that these modern drivers are trustworthy from a security perspective?  Or am I misunderstanding what these patches are doing?

This is not the primary rationale for using ANGLE, and even so, we do all validation in Gecko, before passing validated calls off to the driver.

Also these patches whitelist only very new drivers, and further, only WebGL 2 is using native GL for now. WebGL 1 still goes through ANGLE, and is likely to stay that way for most users.

This bug should be unrelated to this. This sounds related to bug 1002846, though that hasn't landed. I know there is motion around these bits right now though.
bgirard may know more.

Thanks.
Best file another bug and CC me. Also include your full about:support (I'd like to see which preferences you have modified just in case). It would be handy to run a real bisection if you haven't done so already so we can tell what's querying the OGL_LAYERS blacklisting.
