- Scene view audio toggle doesn't work after disabling and enabling audio source component with audio random container
- Pitch changes while paused messes up scheduling of the audio random container
- Crash on detail::ComputeShaderSnippetKey when entering the Play mode
- Unable to interact with Material Inspector window when creating a new Material and renaming it
- Shadow artifact is cast onto GameObjects in the Scene view when the Scene view lighting is disabled
Resolution Note:
This behavior is correct. The key ingredients here are:
- A MonoBehaviour with attribute [ExecuteInEditMode] is using a NativeContainer
- The NativeContainer is being Dispose()'d in OnDestroy of this MonoBehaviour
This means OnDestroy won't be called for the instance of this MonoBehaviour in the editor domain. Moving the dispose code to OnDisable resolves the issue.
