I wanted to start playing Minecraft again but encountered an issue:Normally when you move your mouse pointer to look around it automatically gets centered on screen to track your movements. What happens for me is that it doesn't get centered and every time my mouse updates (moving it a pixel or clicking a mouse button) the player moves his eyes into that direction at the speed that corresponds to the distance off center. The result is identical to this video: . The guy in the video is using a VM that causes it, but I'm on a Windows 8 install.Also note that this happens only after you've pressed any key on the keyboard (wasd,Ctrl, Alt, etc.) and then persists.Also: When I try to move items in my inventory I can't pick them up by single clicking, I have to hold my mouse button which also causes the effect of spreading the items which is quite annoying...What I tried so far to fix the issue:

• Upgrading/Downgrading Minecraft
• Deleting .minecraft
• Altering mouse options (speed, acceleration, ... - pretty much everything)
• Restarting Computer
• Reinstalling Mouse Drivers
• Using another Mouse

I'm using:Windows 8 EnterpriseGeForce GTX 670 (if that's somewhat related)DxDiag: http://hastebin.com/winapayuno.texEdit: I just updated my Graphics Drivers, didn't help at all.Update (SOLUTION):Synergy was causing the issue! (A program that allows sharing screens through multiple computers)I had to stop the service and then it resolved itself!
