[5.6] GUI Errors

[BC_Tim]

Hi,

we updated today to Unity 5.6 and getting a few GUI errors. Example:

Error messages

GUI Window tried to begin rendering while something else had not finished rendering! Either you have a recursive OnGUI rendering, or the previous OnGUI did not clean up properly.

Expected top level layout group missing! Too many GUILayout.EndScrollView/EndVertical/EndHorizontal?
UnityEditor.DockArea:OnGUI()

ArgumentException: Getting control 1’s position in a group with only 1 controls when doing Repaint

Assertion failed on expression: ‘device.IsInsideFrame()’

Because of this errors the rendering of windows like the build settings didn’t work at the first time (it shows a black window). It takes a few seconds to render the window correctly.

Has anyone else similar error messages?

Thanks

I’m seeing the same thing.

I keep seeing what appears to be the exact same 4 error messages in the console:

Disabling the (integrated) plastic scm source control plugin in the editor settings “fixed it” for us. We tested it on 4 machines.

Thank you for following up on it, we experienced the same problem and this “solved” it.

Hi sorry about the error messages. The problem is fixed in 5.6.0p1.
The messages are harmless and just mean the GUI is trying to repaint a window whilst it is in the middle of an OnGUI() method.
It is common to the Unity Version Control windows : PlasticSCM or Perforce.
