In visionOS beta, when using ARKit for image detection, the initially detected AnchorUpdate status is .add, and subsequent detections of the same image are marked as .update. However, after toggling immersiveSpace, the same image is detected with the status .add again. After updating to visionOS 2.1, the first detection status remains `add, and subsequent detections of the same image remain .update, even after toggling immersiveSpace. Could this be due to a change in processing flow?

I understand that the system helps maintain user comfort by automatically adjusting the opacity of content in certain situations, like when someone moves too quickly or gets too close to a physical object. The content in front of them dims briefly to allow a clearer view of their surroundings. And I'd like to know the specific distance at which the system begins to show the physical object, or what criteria are used for this adjustment.

I've been working with ARKit and Metal on the Vision Pro, but I've encountered a slight flickering issue with the mesh rendered using Metal. The flickering tends to occur around the edges of objects or on pixels with high color contrast, and it becomes more noticeable as the distance increases. Is there any way to resolve this issue?
