Editor.OnSceneGUI is not called when hovering the mouse over the Scene window



How to reproduce:
1. Open the attached "" project
2. Open the "SampleScene" Scene
3. Select the "Cube" GameObject in the Hierarchy window
4. Hover the mouse over the Scene window
5. Observe the Console window

Expected result: The method "OnSceneGUI()" is called in the Script "OnSceneGUI_Code" and the message in the Console is printed
Actual result: The method "OnSceneGUI()" is not called and there's no message

Reproducible with: 2019.3.0b6, 2019.3.0f4, 2020.1.0a17
Not reproducible with: 2017.4.35f1, 2018.4.15f1, 2019.2.17f1, 2019.3.0b5

  1. Resolution Note:

    This is normal behaviour, OnSceneGui is called if gizmos for that object are enabled. Gizmos can be disabled several ways: individually through the gizmo menu in the Scene View, all at once through the SceneView gizmo menu toggle and through code via SceneView.drawGizmos

    Does enabling "Always Refresh" under the Scene View toolbar have any effect?

    If you found this issue from a search engine but you're actually looking for the case where OnSceneGUI is not called *at all* even after enabling gizmos, please check this new issue instead:
