When I click the play button, the Minecraft game window shows me a black screen that has flashing textures, of what looks to be a skeleton head, across the screen diagonally. It progressively gets worse and worse with more and more things flashing on and off. After letting it sit for a while it never opened up minecraft.

Console Output:
