The movement speed of an Animation is inconsistent for a single frame when transitioning between Animations
How to reproduce:
1. Open the user's attached "Anim" project
2. Open the Scene "SampleScene"
3. Enter the Play Mode
4. Inspect the created GameObjects' name in the Hierarchy
Expected results: The 3rd parameter (parameters are separated by "_") are steady and similar
Actual results: On one frame the 3rd parameter (which is speed) will be significantly smaller
Reproducible with: 2019.4.27f1, 2020.3.9f1, 2021.1.8f1, 2021.2.0a17
Could not test with: 2018.4.35f1 because of the "Unexpected node type." error

Resolution Note (fix version 2022.1):
Won't fix, as fixing this would require lots of refactoring. This bug happens only when doing root motions and transitioning to a state with a transition duration really small. What would happen, is that it's impossible to evaluate the root motion if a delta time of 0.1s happened for example, but only 0.05 were spent on the previous and next state. Refactoring to give knowledge of the root motion for the previous state would cost a lot in performance for an edge case/ A warning was added to make sure that this case, the transition duration should be bigger than a deltaTime.
Workaround :
1. Use looping clips
2. Make sure that the transition duration is above a deltaTime
3. add an offset to the transition, which will start the next state at least the deltaTime.
The warning has been added in Unity 2022.1.0a6
