Modifying the Particle System component makes the Editor freeze temporarily when another Particle System is attached as a Sub Emitter
Reproduction steps:
1. Open the attached project “EmitterLagSpike”
2. Open Scene “Assets/Scenes/SampleScene.unity”
3. Select the “Particle System” GameObject
4. Make sure that the Particle System is playing or paused
5. In the Inspector enable the “Velocity over Lifetime” module
6. Observe the Editor
Expected result: The module is enabled without interruption
Actual result: The Editor freezes for some time
Reproducible with: 2021.3.29f1, 2022.3.8f1, 2023.1.10f1, 2023.2.0b6
Reproducible on: Windows 11
Not reproducible on: No other environment tested
Notes:
- In step 5 any kind of modification can be made to the Particle System component to make the Editor freeze
- The longer the Playback Time is, the longer the freeze lasts
- If the Sub Emitter module is disabled, the Editor will no longer freeze after any modifications
