STEPS TO REPRODUCE THE ISSUE

Currently, there is a bug where an afterimage appears in the camera background when using the Depth API. (See attached image)

Testing took place in the'HelloAR' demo scene

The afterimage is continuously updated every 5 to 10 seconds, and the occluded object is not properly occluded because it is covered by the afterimage texture.

What I further discovered is that when I disable the'DepthEffect' script the bug goes away. It seems to have something to do with the DepthEffect script.

Is there any way to fix this issue?

WORKAROUNDS (IF ANY)

In Unity 2017.4.40f1, we have confirmed that the Depth API is working properly and functions neatly without afterimages.

It seems unclear whether it is a problem with the Unity version or the Gradle version.
