When I apply a 2D orthographic NGUI UI to sit on top of an orthographic main camera, everything looks fine. But when I press a button that takes the main camera out of orthographic view and into perspective, there is a strange blue skybox rectangle that appears in the upper left corner of the view.
A few things to note:
1. It only happens when I have shadows enabled.
2. It only happens in standalone mode on my Android device. If I try to run it in or from Unity to my remote device, it looks fine.
Any ideas why this is happening?
