Steps to reproduce:
1. Open "Stripped scene.zip" project, "Strength_PUB" scene (from https://oc.unity3d.com/index.php/s/KGG89t0Ty3BiMbb)
2. Open Task Manager to observe the memory
3. Press play
4. Search in the project "fog" and active those particle systems
- Memory leak happens until it crashes

Note: On the full project crashes after few seconds since it's quite big, the stack trace:
