Regression

No

Cloth starts jittering when a related gameObject is selected in the Inspector window while the cloth is moving

Cloth

-

How to reproduce:
1. Open the attached project named "Case_1293351"
2. Open the BrokenCloth Scene and enter Play mode
3. Select the "Cloth parent" gameObject
4. Observe the Cloth cape attached to the Sphere

Expected result: Selecting/Deselecting a gameObject related to the Cloth Component does not have an impact on the Cloth
Actual result: Selecting "Cloth parent" or "Cloth" gameObject causes the Cloth to jitter

Reproducible with: 2018.4.30f1, 2019.4.16f1, 2020.1.17f1, 2020.2.0f1, 2021.1.0a10

Notes:
1. The Cloth component would sometimes jitter when nothing is selected as well. However, it would happen less frequently (~ once a minute on the testing machine) and the jittering would also weaker

    I reported the issue and I would like to note, that this is not about selecting/deselecting the object itself, but selecting object in my project resulted in lowered FPS (many component inspectors to process), so the problem should be related to the number of physic updates per frame updates.
    In short, number of FPS affects cloth behaviour.

    The same here, it seems that on 2019.4.26 cloth is overall less stable than on 2018.4 Seems like virtual particles don't work at all?
