[Shuriken] Particle travels a shorter distance when in Play Mode

Visual Effects - Legacy


How to reproduce:
1. Open project from the attached file ""
2. Open the Scene View and select "Particle System" GameObject in the Hierarchy
3. Press Play in the lower right corner window in the Scene View
4. Inspect the distance that the particle travels in the Scene View
5. Enter play mode and play the particle again
6. Inspect the distance that the particle travels in the Scene View

Expected behavior: particle travels the same amount of distance
Actual behavior: particle travels a shorter distance

Reproducible with: 2018.4.26f1, 2019.4.6f1, 2020.1.0f1, 2020.2.0a19

- Also reproducible in the Game View
- Random Seed is set to fixed seed (0)

  1. Resolution Note:

    We use a slightly different timestep in Edit Mode vs Play Mode for previewing vs. simulating particle systems. honestly I've no idea why we do this, but for some reason it's hard to change (it breaks some other things) and we want to keep risky changes to a minimum for the Particle System, as it's mostly just getting bugfixes now. Sorry for the bad news, but we've decided not to fix this bug. we do appreciate the report though!
