Shader Complexity shows checkerboard screen in Android ES 3.1 render

Changing the view mode to Shader Complexity while in Android ES 3.1 preview render will show a black and grey checkerboard in the viewport. 

This does not happen in UE 4.27

1. Create a blank project with start content
2. Go into the settings and change the Preview Rendering Level to Android ES 3.1
3. Change the view mode to Shader Complexity

Actual Result: Black and grey checkerboard when Shader Complexity is enabled

Expected Result : Viewport shows the level with color showing the Shader Complexity.
