(This is a spin-off from bug 1435693.) Please never set a priority. ;-)

Can you post the graphics section of your about:support?

The Gen 5 Ironlake GPU that you have does not support D3D feature level 10.1. Feature level 10.1 is currently required by ANGLE to expose OpenGLES 3. We don't have any plans to lower the requirement until we switch away from using ANGLE and use D3D directly.

I don't think we need to fix this to enable WR on nightly.

We also don't need to fix this for v1 since it's an Intel GPU.

P3 ?

Sure. I don't think it matters much right now if it's not blocking the stage-wr-nightly or stage-wr-trains bugs.
