iOS two cameras with anti-aliasing blacksreen

I have a simple scene with two cameras, a light source and some 3D Objects. When I add anti aliasing, one of the two cameras show only a black screen. When I remove the light source everything works fine. I’m using Unity5 and the error happens on iOS. Is there a workaround?

QualitySettings.antiAliasing = 2;

Edit: The blackscreen only appears when the light source (type directional) also have a shadow type of soft or hard.

I’m having the same issue. In a scene with two cameras, one with clear flags set to “depth only” and another one in the background with a lower depth. The back camera just renders everything in black, if AA is enabled. If I add more cameras, all the cameras except the one in front with the highest depth render only black.
