Motion Blur has sharp edges when object is moving in the foreground of another object
Steps to reproduce:
1. Open the attached "Repro" project
2. Open "MatrixPrevious" Scene
3. Enter Play mode and observe the moving GameObjects
Actual results: Motion Blur of moving GameObjects has sharp edges when when they are moving in the foreground of a Plane GameObject
Expected results: Motion Blur has smooth edges
Reproducible with versions: 2022.3.50f1, 6000.0.23f1
Could not test with: 2021.3.44f1 (due to entities package errors)
Tested on (OS): macOS Sonoma 14.5 (Intel)
Notes:
- Issue is also reproducible in the Player
- Issue is not reproducible on Windows 11 Pro
- Issue is only reproducible when the non-moving GameObject is positioned below moving GameObjects
- Issue might appear after 2-3 minutes depending on the speed of the moving objects

Resolution Note:
The algorithm is working as designed. This is an occlusion problem that exists in the motion blur implementation of all existing engines.
We'd need to make a new motion blur effect to solve this problem and right now this is not something we plan to investigate
