Problem with NGUI Unity 2D Sprite across devices

[Omega]

I've posted this at http://gamedev.stackexchange.com/q/93518/4779 as well, but figures this is the better place for asking this.

I have a problem with NGUI for Unity, using the Unity 2D Sprite objects.

First, have this image:



And then create an NGUI Unity 2D Sprite object in the scene. Apply this image and you get this:



Very odd. This doesn't happen if you use an Unity UI Image object or a SpriteRenderer component. But I really need to use NGUI's Unity 2D Sprite.

Then I ran the scene in several devices. Some of them display the sprite correctly - but others do not. Look:

• Top-left device: iPad Mini 1: The sprite is bad.
• Top-right device: iPad Mini 3: The sprite is good.
• Bottom-left device: iPhone 5c: The sprite is bad.
• Top-right device: iPhone 6 plus: The sprite is good.

I fail to understand what is the problem.

Again, this doesn't happen with sprites rendered with SpriteRenderer or Unity's builtin UI Sprite system. However, I need to do this with NGUI.

NGUI has a "NGUI Sprite" which I believe does work. But I don't want to use that one - I need to use the "NGUI Unity 2D Sprite" option.

Any ideas?

Using Unity 5.0.0b20

Found the solution.

In the inspector, uncheck "Generate Mip Maps", and it will now work.

I do not know if such behavior is expected of NGUI. Perhaps it is a bug of some sort? Either way, I'm good now .
