You're welcome

Yes, that resolved the issue! Thank you very much for your time.

Hi,

after trying out your setup, I've successfully tested this workaround;

just add the following simple script to your GUITexture objects:

using UnityEngine;
using System.Collections;

public class NoStretch : MonoBehaviour {
	
	void OnRenderObject()
	{
		GL.Viewport(new Rect(0,0,Screen.width,Screen.height));
	}
}

This solved for me (using the Cloud Reco sample with a GUITexture).

Got it from your PM, thanks.

I've just built a minimal project based on the Cloud Reco sample. I am seeing the same issue when scanning. What's the best way to get the project to you? Dropbox?

Built in Unity 4.6.3

Xcode 6.2

Vuforia 4.0

Could you provide a minimal repro-case setup to reproduce this ?

For example, starting from the Cloud Reco sample, would a single guiTexture element be sufficient to reproduce this ? 

any additional details would help..

Sure. I am building the UI with guiTexture and scaling based on screen size and placing with Vector3.

Could you describe your setup a bit more in depth ?

are you drawing your GUI with the OnGUI() method of MonoBehaviour ? or are you using the Unity 4.6 UI system ? 

Thanks for the reply and suggestion, Alessandro. Unfortunately, adding the GL.InvalidateState(); call did not fix the issue on the iPad Air 2. Do you have any other suggestions? This is a big issue for me.

Hi, the fix in the thread https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/vuforia-40-and-unity-50 refers to Unity 5,   not Unity 4.6

One quick thing you could try is to add this call right after the line GL.IssuePluginEvent(-1);:

GL.InvalidateState();

and see if it makes a difference.

Update: The above fix seems to be working on a iPhone 6 Plus, but not on an iPad Air 2.
