Animation playback speed on entering Play Mode is faster than the consecutive playbacks

Animation

-

Steps to reproduce:
1. Download and open the project "UnityAnimationToQuickBug.zip"
2. Open Scene "GamePlayScene.unity"
3. Open the Animator Tab (Window > Animation > Animator)
4. In the Inspector Tab, click on "ImageBoxCarousel" GameObject under "CanvasForImageBox" GameObject
5. Enter Play Mode
6. Notice the MoveLeft Animation State's playback speed on entering the Play Mode and again during its second playback

Expected result: The MoveLeft Animation State's first playback speed on Entering Play Mode is the same as the second playback speed
Actual result: The MoveLeft Animation State's first playback speed is faster than the second playback

Reproducible with: 2019.4.29f1, 2020.3.14f1, 2021.1.15f1, 2021.2.0b4
Could not test with: 2018.4.36f1 (No SpriteLibraryAsset)

  1. Resolution Note:

    This is caused by mono jit compilation done the first time you go to play mode which have an impact on overall performance.

    You can use the new Editor options: Projects setting/Editor/Enter Play mode options to change this behaviour and enable fast play mode.
    check Enter Play mode options
    uncheck reload domain
    uncheck relaod scene

    There is a few drawbacks with this new options so please reade documentation carefuly to see if it suitable for your project.
