[Animation] GameObjects parented to an animated GameObject shake when the scale is not 1

--

-

How to reproduce:
1. Open the attached project "1375437 UI display Issue EmptyProject.zip"
2. Open SampleScene and enter Playmode
3. Observe the objects on the right
4. Wait some seconds for the animation to start

Expected result: The animation is played without issues
Actual result: Scaled objects on the right side of the screen are shaking during some parts of the animation (See attached Repro.mp4)

Reproducible on: 2020.3.42f1, 2021.3.15f1, 2022.1.24f1, 2022.2.0f1, 2023.1.0a21

  1. Resolution Note:

    This is a limitation of the transform system caused by floating point numbers used to store transforms.

    As a workaround, you can try either:
    - Reimport your models without scale factors to make sure you limit operations that could end up in loss of precision.
    - Organize your world in cells. Instead of moving your object in an ever increasing world, you shift the world as your character reaches a new cell.
