GameObjects appear jittery when moving slowly in the Game view
How to reproduce:
1. Open the attached project
2. Open Scenes/SampleScene
3. Go to the Game view, press the Play button, and observe the GameObject moving
4. Open Scenes/SampleScene1
5. Go to the Game view, press the Play button, and observe the GameObject moving
6. Open Scenes/SampleScene2
7. Go to the Game view, press the Play button, and observe the GameObject moving
Expected result: the GameObjects move smoothly without noticeable jittering
Actual result: the GameObjects move with noticeable jittering
Reproducible with: 2019.4.31f1, 2020.3.19f1, 2021.1.23f1, 2021.2.0b14, 2022.1.0a11

Resolution Note (2022.1.X):
This issue is due to rasterization (aliasing) and resolution. Objects representation moved, but rasterization only cares about pixel centers so when the objects triangles enters or exits a pixel center it will look like it jitters. Especially if top and bottom of the object does not enter/exit the pixel center at the same time.
This is nothing we can do about on the rendering side, and can probably only be mitigated by increased resolution, anti aliasing techniques and/or content where gracing angle effects (such as Fresnel terms) are minimized.
