        From the navigation bar's button I start an UIAlertController with the style UIAlertControllerStyleActionSheet. When I touch on one of the choices I get the following message:

         

        [Warning] <_UIPopoverBackgroundVisualEffectView 0x7fe07a420080> is being asked to animate its opacity. This will cause the effect to appear broken until opacity returns to 1.

         

        This message only appears when the controller is closed for the first time. Afterwards, the message does not appear anymore. What is the meaning of this message? I am not explicitely controlling the drawing behaviour (opacity) of the UIAlertController at all nor do I do any other layouting or animations with it.
