Hello, Just recently I updated to windows 8.1 and for some reason Minecraft doesn't seem to work anymore... It worked fine in windows 8 but now it doesn't! When minecraft is open everything is fine, but when I load a world the gui flickers and items flickers, and the screen flickers on top of all that! So yeah I have no idea how to fix this problem!
Here is a Video of the Problem:
Here is my DxDiag log:
