When running AR content, the texture from the camera that gets rendered is flashes of different colors, probably from camera, looks like it's taking one pixel and applying that to the entire canvas.

I've encountered this on a Pixel 1, and then it started working subsequently for me. Maybe an intermittent. Others have reported this occuring on a Pixel 2 and 3:

https://github.com/googlecodelabs/ar-with-webxr/issues/8#issuecomment-431939338

What steps will reproduce the problem?
(1) Enable webxr/webxr hit test flags
(2) Go here on an AR enabled device: https://googlecodelabs.github.io/ar-with-webxr/final/
(3) Start the AR session

What is the expected result?

Should render the camera texture in the XRPresentationContext. Sometimes this happens.

What happens instead?

"Random" colors in the canvas instead.
