Hello developers:
I would like to share a problem I encountered when developing a camera application using camerax.
a part of preview view of camera display on the screen unexpected. as you see the photo.

Click the test button for the second time to select the mp4 file to play and it will be displayed normally.
But when I go to the desktop and come back, the error appears again.

Hi Leong,  
This is probably a bug in SurfaceView. 

Can you try to set the implementationMode to COMPATIBLE before bindToLifecycle call like the following ? 

`preview.setImplementationMode(PreviewView.ImplementationMode.COMPATIBLE)`

Thanks Scott,
It work.
In addition, I found that many mobile phones have similar problems.
