VR mode breaks picking

1. A concise explanation of the problem you’re experiencing.

Visiting VR mode (scene.useWebVR) breaks scene.pick. Nothing gets picked after returning from VR to normal mode.

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

This is normal 3d tiles feature picking demo, only change is that vrButton has been enabled. If you visit VR-mode and come back, feature picking does not work anymore.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

4. The Cesium version you’re using, your operating system and browser.

Cesium 1.60, Windows 64 bit, Chrome

Thanks for the Sandcastle. This does look like a known issue, I’ve bumped the bug report on GitHub here:

I also post some debugging thoughts there that might help looking into this further.
