How to reproduce:
1. Open the user's attached project
2. Open scene Scenes/SampleScene
3. Press the Play button and observe the Game view
4. In the Hierarchy window, select the GameObject "TestPS"
5. In the Inspector view, under the Particle System component, select the Renderer module
6. Set the Cast Shadows setting to "On"
7. Observe the Game view

Expected result: the test texture (Particle) remains fully blurred
Actual result: the test texture (Particle) is only partially blurred

Reproducible with: 2019.4.32f1, 2020.3.21f1, 2021.1.27f1, 2021.2.1f1, 2022.1.0a13

Notes: the Particle flickers when Shadow casting is enabled from 2021.2.0a21 onwards
