Color Picker Causing Errors. (Repeatable in new, empty project)

How to reproduce in 5.4 beta 17 (also happened in beta 16):

Open new Unity project.
Select the camera and then select the color picker in the inspector.
Change the color to anything.
Hit play to run the app.

Here is what I get every time:

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

rc.right == m_GfxWindow->GetWidth() && rc.bottom == m_GfxWindow->GetHeight()

I believe it's from advantage to report bugs using the "Report a Bug" functionality in Unity. This makes sure that the bug-report gets into their QA pipeline, which might not be the case if the bug-report is a forum post.

 

I found this just prior to leaving for work so didn't have time to post from Unity. I posted this from work, but will post from within Unity this weekend.

Has anyone else been able to reproduce the error?

 

Something you might want to add to your bug report. The same behavior can be observed when doing the following:

1. Have any component with a color picker (doesn't need to be a Camera)
2. Select a color from outside of Unity (say from your browser)
3. Play

Restarting Unity fixes it.

 

Created bug report.

Thank goodness you figured out it was the color picker! This error is driving me nuts!

 

FYI, that one from @jeffweber was closed duplicate.
