GUI Layout 'Fading' on changing QualitySettings

Hi there, I have a menu with a button that changes Anti Aliasing Settings on and off (from x0 to x4) however when I push this button my GUILayout of Buttons seem to fade out. I have decided to remove everything from my scene apart from a camera and a GUIText (the GUI text is part of my FPS reader) and I still get this problem.

I can navigate the entire menu and change resolutions without the same effect.

One the effect occurs I haven't found a way to get rid of it, it persists even when AA is changed back.
The code works fine on PC.

This is my code, I'm running it on a Nexus 10.

Code (csharp):

1.

3. using System.Collections;

If you're developing for iOS/Android you should especially get away from the bad performance of Unity's built-in GUI and invest in NGUI. There is even a free edition. It will solve your problems too.

 

I'm curious about this free edition, could I get a link I did a quick search and couldn't find it

Thanks

 

Any chance of getting a location of this free edition?
