1580258 - WebGLContext.MakeXRCompatible needs to switch to the device connected to the XR hardware

Status: RESOLVED WONTFIX

(Core :: WebVR, task, P2)

Description

[:kip (Kearwood Gilbert)]

The WebXR Specification requires WebGLContext.MakeXRCompatible to ensure that the WebGLContext is ready for use with an XR session:

https://www.w3.org/TR/webxr/#dom-webglrenderingcontextbase-makexrcompatible

In some cases, the GL context will need to be dropped and re-created for a GPU that is connected to the XR display.
