Strange display on idle

[Yuri]

Hello all!

I am new to Unity and also NGUI. I have started working on a 2D game by using NGUI and now I am facing following problem: everything seems to work ok on Unity player, but when I run it on a device (e.g. tablet) I get strange results after a short period of time with no interaction (something like idle).

I have attached some screenshots in order to see what is happening.

Can anyone help me with this problem?

Thanks in advance!

Disable Multi-thread rendering. That feature is bugged in Unity and should never have been enabled.

Thank you very much, Aren!

That was, indeed, the problem.
