ArgumentException: GUILayout: Mismatched LayoutGroup.Repaint

[dis]

Hello!

1. Create empty object
2. Add UITexture
3. Add UIStretch
4. Disable UITexture (uncheck the checkbox in inspector)
5. Start program.

The described error appears even if UIStretch is also disabled.

Line 44 in UITextureInspector.cs
Texture tex = EditorGUILayout.ObjectField("Texture", mTex.mainTexture, typeof(Texture), false) as Texture;

Unity 4 changed something inside of it that cause these to appear sometimes. I always get this kind of a GUILayout error when adding a new sprite to an atlas in Unity 4, for example. Unity 3 works as expected, so it's a regression issue in Unity.

Either way it seems harmless, and an editor-only issue.

Oh, I forgot to mention that I use Unity Version 3.5.7f6. It seems the error appears on editor only.

Dis, Arenmook - I'm running into the same problem - did you ever figure out what was causing it? I'm also not on Unity 4.

[ArenMook]

Nope, and I am not running into it in 4.1, so perhaps something in 3.5.x?

[cbartlett]

Im running into it in 4.1

[kfboelter]

4.1.5f1 here...

Any news on that?
Still harmless?

[kreso]

Unity 4.3 here - this is still happening (when creating a new sprite collection). It seems harmless except that there is a red warning in the console.

ArenMook, is this article perhaps related? http://forum.unity3d.com/threads/158375-Unexplained-GUILayout-Mismatched-issue-is-it-a-Unity-bug-or-a-miss-understanding

[ArenMook]

I've seen even Unity's own components trigger that (mainly ones that involve parts of the inspector window scaling in/out). It's some harmless issue that is thankfully rare, and completely harmless (which is likely why it doesn't get fixed).
