Issue ID




OnSceneGUI is not being called when using a certain layout

Scene/Game View


Reproduction steps:
1. Create a new project
2. After Editor loads shut it down completely
3. Open project root and navigate to Library folder
4. Replace "CurrentLayout-default.dwlt" with the one attached in edits
5. Open the project again
6. In the scene create a new empty GameObject at (0, 0, 0)
7. Attach the "SceneGUIExample.cs" script to the object
8. Select the GameObject and inspect the Scene

Expected result: OnSceneGui is called and there is a rectangle wireframe in the scene at GameObject's position
Actual result: OnSceneGui is not called and there is no rectangle wireframe in the scene GameObject's position

Reproducible with: 2021.1.15f1
Not reproducible with: 2018.4.36f1, 2019.4.29f1, 2020.3.14f1, 2021.2.0b4, 2022.1.0a3

1. looking at a diff tool the layout file where the issue reproduces is mostly different in some of the values (not by a great margin). Some lines seem to be missing, though the file does not appear corrupted or anything of the sort.
2. I am not sure if the issue here is OnSceneGui not working with the layout, or the layout being somehow edited during the game creation process so that the issue starts reproducing.
3. An upgrade of the project might resolve the issue, but I did not find it consistent

  1. Resolution Note (fix version 2021.1):

    Fixed having 2 inspectors (1 Normal and 1 Debug) open on the same object causing inconsistent behavior regarding the call of OnSceneGUI and other Editor scripts methods.

    Another workaround/fix is to save your current layout, and reloading it.
    I used 2019.4.10f1

    This happens when the last (going from left to right and top to bottom) inspector in the layout is a "debug" inspector. Still reproducible in 2021.1.24f1.

    Workaround that helps me: I have a left and a right inspector. Usually the "normal" inspector is on the left and the "debug" inspector is on the right. Switching them around (just change their type in the view's menu) lets OnSceneGUI be invoked again. No new layout or tab closing required.

    Been searching around on google for days!

    Workaround for users stumbling upon this until this is fixed:
    a. Load another layout (a previously saved one if you know it's not corrupted, or a default one)
    b. Close *all* Inspector tabs, and reopen one
