[0.4.3+] Changing MSAA at runtime?

Right now, if I change QualitySettings.antiAliasing at runtime, nothing happens. If I make small modifications to OVRDisplay.cs to allow reconfiguring the eye textures by releasing the existing rendertextures and then creating them as usual via ConfigureEyeTexture(), I get a black screen and no errors to look at.

Is there a recommended approach to accomplishing this? Any help is appreciated!

Details of what I tried:

New method added to OVRDisplay.cs (logic taken from bottom of OVRDisplay()):

	public void ReconfigureEyeTextures()
	{
		for (int i = 0; i < eyeTextureCount; i += 2)
		{
			ConfigureEyeTexture(i, OVREye.Left, OVRManager.instance.nativeTextureScale);
			ConfigureEyeTexture(i, OVREye.Right, OVRManager.instance.nativeTextureScale);
		}
	}

Calling new method at bottom of OVRDisplay() in place of the old logic:

		ReconfigureEyeTextures();
	}

In ConfigureEyeTexture(), inserted the following just prior to newing up the RenderTextures:

		if(eyeTextures[eyeIndex] != null)
		{
			eyeTextures[eyeIndex].Release();
			eyeTextures[eyeIndex] = null;
		}

A test script to try cycling MSAA:

		if(Input.GetKeyDown(KeyCode.J))
		{
			if(QualitySettings.antiAliasing == 0)
				QualitySettings.antiAliasing = 2;
			else if(QualitySettings.antiAliasing == 2)
				QualitySettings.antiAliasing = 4;
			else if(QualitySettings.antiAliasing == 4)
				QualitySettings.antiAliasing = 0;

			if(OVRManager.display != null)
				OVRManager.display.ReconfigureEyeTextures();

			Debug.Log("QualitySettings.antiAliasing = " + QualitySettings.antiAliasing.ToString());
		}
