Google Cardboard setVRModeEnabled (false) displaying nothing

I am working on an application and am modifying the treasure example code. I have a visual effect that is not working correctly that I would like to debug. This is difficult to do in stereo. It seems I can just call cardboardView.setVRModeEnabled (false); in onCreate () and it would not perform distortion correction and would only do one eye. That would be great.

However, everything I see is black.

I reduced my onDrawEye () to just:

glClearColor(1.0f, 0.0f, 0.0f, 1.0f);
glClear(GL_COLOR_BUFFER_BIT);

      

        
        
        
      

    

When setVRModeEnabled is true my screen is red. When it is false, everything I see is black. Any ideas?
