Mac- Screen shot solid black, ARAM Orianna ball is invisible

Orianna's ball becomes invisible after a while in ARAMS. The ball is only invisible when it is on me. I can q and still see it. I'm not entirely sure what is causing this to occur. I do know it has happened every single time i have played ARAMS except for once while playing . I did take a screen shot of this, but I am on the new client and for some reason the screen shot was solid black.
