I have never heard of such a problem, from which device do you play?
I've figured the problem. The glitches appears only in full screen mode. It's like screen crashes for 0.01 second every time, but in windowed mode all's fine. And no, I couldn't catch it with a screenshot. Also in full screen mode I get square resolution with black lines on the sides, like when you run a PS1 game on a wide screen or something. I don't know how it supposed to be, but my default resolution is 1600x900
