After update 0.40 starting game screen is Ok, but after it screen artefacts appears so no heroes or game menu is visible, square artifacts across the surface of the earth and sky. Video driver updated to newest, tried to change game settings - vsync (yes/no), windowed, fsaa changed - all rendering options have been changed but nothing.
