-

Reproduction steps:
1. Open the attached “BugRepro” Project
2. Open the “Assets/Scenes/Scene” Scene
3. In the Hierarchy window, select “SceneLoader“ GameObject (FirstScene > SceneLoader)
4. Open the Animator window (Window > Animation > Animator)
5. Enter Play Mode
6. In the Animator window, observe the “SceneFadeIn” animation state progress

Expected result: The animation plays at a constant rate
Actual result: The animation freezes at a random point and unfreezes after a short amount of time (around 1 second) while playing

Reproducible with: 2021.3.36f1, 2022.3.22f1, 2023.2.16f1, 6000.0.0b13

Reproducible on: Windows 11
Not reproducible on: No other environment tested

Notes:
- The Editor sometimes crashes when entering/exiting Play Mode
- “Reload Domain” setting can be disabled in Editor settings (Project Settings > Editor > Enter Play Mode Settings), to better see the issue

  1. Resolution Note:

    The project is loading several huge textures. While most of image decoding happens on background thread, the final integration of the texture happens on main thread and this time is sizeable due to huge size of textures, hence the main thread is blocked and you can notice it.
