I can't draw correct circle at Portrait mode.
I find shape, but not circle, just line. like this.

How can I draw correct circle for face landmark at Portrait mode?

I only fixed two things.

1. Check Portrait at Device Orientation. (and select target iOS 13.2. but this setting is maybe unrelated this problem)

2. Add "AVCaptureVideoOrientation.portrait"

I checked #5 but I can't understand this problem.

My Environment

MacOS Catalina 10.15.2
Xcode 11.3.1
iPhone7 (iOS 13.3.1

I decided to try to use CIFaceFeature each sampleBuffer frame.
But poor accuracy
