Visual effect glitches when using "Conform to sphere" with high attraction force values in VFX graph and clicking in the Scene view

-

Reproduction steps:
1. Open the attached project “VFX_BOOM”
2. Open “Assets/Published/Alexander Baggett/Electric Shield/DemoScene/demoScene.unity”
3. Open “Assets/Published/Alexander Baggett/Electric Shield/VFX/ElectricShield_VFX.vfx” via double-click
4. In the “Update Particle Strip” block, within “Conform to Sphere” change the value of property “Attraction Force” to 900
5. Click multiple times in the Scene view

Expected result: Effect plays uninterrupted
Actual result: Effect behaves differently on each click

Reproducible with: 2020.3.46f1, 2021.3.21f1, 2022.2.10f1, 2023.1.0b7, 2023.2.0a6

Reproducible on: Windows 10

  1. Resolution Note:

    Using high values for forces can lead to glitches like this due to time quantization. This will be mitigated when improving stability by implementing subframe interpolation / improving time integration. In the mean time, using a fixed step dt for the FX update might help.
