Issue ID

UUM-102553

Regression

No

UI Document gets stuck in the original state when the UI GameObject is disabled and re-enabled

-

How to reproduce:
1. Open the “UIDocumentStuck.zip“ project
2. Open the “FlightScene“ Scene
3. Enter Play Mode
4. In the Hierarchy, select the “GO1” GameObject
5. Disable and re-enable the selected GameObject in the Inspector
6. Observe the Game view

Expected result: The UI is updated to show a black bar with numbers (correct) and with colored bars
Actual result: UI displays only a black bar with numbers (incorrect), but is not updated to show colored bars

Reproducible in: 2022.3.61f1, 6000.0.46f1, 6000.1.0b14, 6000.2.0a8
Could not test in: 2022.1.X (too many package dependency errors)

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Workaround: Open the “Assets/_Scripts/Ships/ShipUI.cs“ script in any IDE and uncomment lines 53-64

Notes:
- Could not reproduce on a new project
- Might be another bug, after doing all the steps, if the UI Document is disabled, the expected results are yielded
- Disabling and re-enabling the UI Document GameObject also reproduces the issue
- The current UI is in world space, but this can be reproduced in screen space as well

  1. Resolution Note:

    The intended workaround was found, which is to put the logic in OnEnable. This is described in the documentation here under "Lifecycle of UI Document components" https://docs.unity3d.com/Manual/UIE-create-ui-document-component.html

    We will strive to document this behaviour and scenario better in the future.
