I get so tired of Editor leaks. Every time I hit Play, I get chaff in the console. Well, not EVERY time. Just any time there's an object selected. Or an Inspector tab is visible. Or I use a package from <somePublisher>. Or some other mystical dance-in-the-moonlight coincidence I can't reproduce in a small project. Code (CSharp): NullReferenceException: Object reference not set to an instance of an object UnityEditor.SceneView.CallOnPreSceneGUI () (at /Users/bokken/build/output/unity/unity/Editor/Mono/SceneView/SceneView.cs:3693) UnityEditor.SceneView.DoOnPreSceneGUICallbacks (UnityEngine.Rect cameraRect) (at /Users/bokken/build/output/unity/unity/Editor/Mono/SceneView/SceneView.cs:2248) UnityEditor.SceneView.DoOnGUI () (at /Users/bokken/build/output/unity/unity/Editor/Mono/SceneView/SceneView.cs:2330) UnityEditor.SceneView.OnSceneGUI () (at /Users/bokken/build/output/unity/unity/Editor/Mono/SceneView/SceneView.cs:2255) UnityEngine.UIElements.IMGUIContainer.DoOnGUI (UnityEngine.Event evt, UnityEngine.Matrix4x4 parentTransform, UnityEngine.Rect clippingRect, System.Boolean isComputingLayout, UnityEngine.Rect layoutSize, System.Action onGUIHandler, System.Boolean canAffectFocus) (at /Users/bokken/build/output/unity/unity/ModuleOverrides/com.unity.ui/Core/IMGUIContainer.cs:351) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&) (at /Users/bokken/build/output/unity/unity/Modules/IMGUI/GUIUtility.cs:189) Notice all the /Users/bokken stuff, that's not my username. That's Unity's MacOS build CI/CD platform, I guess. None of the code here is code that I have access to. None of it points any blame at anything I am doing, so I can stop doing it. It's just chaff. If you can't tell me a line of code or a package that I have any control over, just suppress the message by default.
