[VFX Graph] Particle Strip jitters in the Scene and in the Preview window
How to reproduce:
1. Open the user's attached "test VFX GRAPH 2020.1.zip" project
2. Open the "strip flipbook" Scene
3. Observe the "Visual Effect" GameObject in the Scene view
Expected result: Particle Strip does not jitter
Actual result: Particle Strip jitters
Reproducible with: 10.2.2 (2020.2.2f1), 11.0.0 (2021.1.0b3, 2021.2.0a2)
Could not test with: 2019.4.18f1 (Due to Visual Effect not working when downgrading)

Resolution Note:
The problematic behavior I see when trying to reproduce is the stretch lines that go across the strips.
This is not a bug per say, just that the provided graph is not correct : the texIndex is set Per-particle, and thus changes vastly along the strip, hence the streched UVs.
The jitter visible in the repro video is due to the fact that the flipbook provided has an empty first frame.
