Hi i am a mac user and when i’m playing some games, the characters, structures and minions, they blink (disappearing and appearing). Before, it didn’t happen to me in the game.
These visual glitches have persisted on Mac OS X for over a year, there is no fix unless developers choose to put resources into fixing them.
If I were you I’d post on that topic as well, it can’t hurt even though no fix is in sight.
Of course the unofficial fix is installing Windows through the Bootcamp feature in Mac, and playing without blinking and glitches.
