GameObjects begin to stutter when manipulated after reopening the Player after it was sent to the background multiple times on VisionOS
How to reproduce:
1. Open the attached “IN-109452.zip” project
2. Build and Run on VisionOS
3. Pinch and Hold the Blue Cube GameObject and move it around
4. Minimize the app by going back to the Home Screen
5. Repeat Steps 3 and 4 a few times and observe the Cube each time
Expected result: Consistent performance and smooth movement of the held GameObject
Actual result: GameObject starts stuttering when moved and worsens after each time the app is minimized and maximized again.
Reproducible with: 2.2.4, 2.2.5 (6000.0.54f1), 2.3.1 (6000.0.54f1, 6000.1.14f1, 6000.2.0b12, 6000.3.0a3)
Reproducible on:
Apple Vision Pro on VisionOS 2.5
Testing environment: macOS 15.5 (M3 Pro)

Resolution Note:
This appears to be a native visionOS bug.
Have a native metal visionOS app and register a onSpatialEvent. If you monitor the rate at which data flows into that closure while dragging, it will fall off every time you background and foreground the app using the digital crown. It starts a 90 events/sec, then as you cycle it goes to 45 events/sec, then 30 events/sec, then ~22 events/sec. (Looks a lot like 90/n where n is the number of times you background/foreground).
