UI Ghost Trails

[Alec]

Hi there,
I downloaded NGUI today and was following along with the starter tutorial and came across some weird refresh issue (or whatever the problem is). The image attached describes what's happening. If I drag a UI element across the scene window, the game window doesn't seem to be refreshing properly. I just tried the two controls at random to see and the behavior is consistent.
I've save and restarted Unity as well as restarted my computer, just in case, but the same thing is happening.

I'm using a GeForce GTX 780 on Windows 7 x64 and the Unity 4.34f1. The project is a new standard project with only the NGUI assets added.

Any ideas what might be causing this?

Thanks,
Alec

This seems to have resolved itself. After closing the game tab, saving the project, then closing Unity, I opened Unity and added the game window back to the project and everything was good again. It was weird that the problem was persistent until I undocked the game tab but...problem solved. I'll keep an eye on it.

You must make sure that the first camera to draw actually clears color or skybox, not just depth.
