Twinkle faces of the characters (L.A. Noire)

Good day to you all, comrades. Faced with the problem of flickering faces in LA Noire. The fact that those characters are not always, but periodically flicker some black squares and lines. Not to say that this problem spoils the game experience, but still play a little bit uncomfortable. Especially in LANoire made great facial expressions and she plays a big role, and sometimes this flickering does not normally see the character's face. Help to solve this problem.
