Running sample has green overlay over camera, how to remove it?

Hi,
I am running the example code, but the camera has been overlayed by green screen with normal rectangular screen on top right corner. How to remove the green overlay?

Thank you

Just use this in initCamera in ArActivity.
This solves my two problems.

1. Green overlay over camera.
2. Camera view is stretched(people and objects are distorted).

List<Camera.Size> mSupportedPreviewSizes = camera.getParameters().getSupportedPreviewSizes();
Camera.Size mPreviewSize = getOptimalPreviewSize(mSupportedPreviewSizes,metrics.widthPixels,
metrics.heightPixels);
Camera.Parameters parameters = camera.getParameters();
parameters.setPreviewSize(mPreviewSize.width, mPreviewSize.height);
camera.setParameters(parameters);
camera.startPreview();
arCamera.setCamera(camera);

I am getting this issue in Redmi devices.
