This is a tracker bug. The switch to USE_ANGLE_WEBGL and enablement of WebGL 2 seems to have introduced several regressions for one of our Tech Preview users, including some that are not related to WebGL at all. It seems ANGLE is failing to initialize EGL for at least some users, which was not a problem before; this might be to blame for *all* of the problems? Hopefully we can investigate and resolve the regressions.

If we successfully solve these problems, then we should tell Brent that it's time to land https://github.com/WebKit/WebKit/pull/7079. Otherwise, we might decide to revert the use of USE_ANGLE_WEBGL and ENABLE_WEBGL2, but hopefully it won't come to that.
