How to reproduce:
1. Open the attached “IN-96604.zip” project
2. Build and Run
3. In the Player, observe the VFX effect going up from the projector that is tracking the moving “Car” GameObject

Expected result: Continuous playing of the VFX without issues
Actual result: Visible flickering is observed

Reproducible with: 2.0.4 (6000.0.42f1), 2.1.2 (6000.0.42f1, 6000.1.0b10)
Couldn’t test with: 1.3.11 (2022.3.60f1) - Compilation errors due to downgrading of package and usage of unsupported functions/methods for that version, 2.1.2 (6000.2.0a6) - VFX GameObjects not present in the Player

Reproducible on: Apple Vision Pro 2.3.1

Testing environment: macOS 15.3.1 (M3)

Notes:
- Not reproducible in the Editor and Standalone Player
- Using PolySpatial 2.0.4 the VFX column effect is no longer present in the Player, however the issue is observable with the projection effect in the same place in the Scene, reproduction video attached in the internal notes, showcasing the differences.
