2017.2 new tango api crashes with ARBackgroundRenderer about tango-examples-unity HOT 3 OPEN

https://forum.unity3d.com/threads/new-buildin-tango-api-crashes-in-2017-2-0b4.486324/#post-3176970
I'm using the example provided here.

from tango-examples-unity.

It's able to connect Tango now after I check the XR settings.
But it crashes if I use the ARRenderSetup.
