Reproduction steps:
1. Open the attached “ASDQWE” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. In the Hierarchy Window, Disable the “Light 2D” Spot Light
4. Observe the Scene View
5. Enable the same “Light 2D” Spot Light
6. Observe the Scene View
Expected result: Disabling and enabling the Spot Light had an effect on the lights and shadows
Actual result: Only enabling the Spot Light had an effect on the lights and shadows
Reproducible with: 2021.3.29f1, 2022.3.6f1, 2023.1.6f1, 2023.2.0b2
Reproducible on: Intel macOS 13.4.1
Notes:
- The difference in the lighting is also visible when undoing the reproduction steps (Control-Z) and reopening the Scene
- The issue is not visible when the Overlap Operation is set to Additive
- Before the third step is made, enabling or disabling the “Shadows” Property of the “Light 2D” Component has no effect on the Spot Light
- After the reproduction steps are made, the “Lught 2D (2)” Spot Light is not evaluated. Following the reproduction steps on that Object, results in the “Light 2D” Spot Light not being evaluated
- In the 2021.3.29f1 and the 2022.3.6f1 versions, it is additionally required to enable the “Light 2D > Shadows > Strenght” on all the light sources
