Windows 8.1 comes with a yet unsolved mouse disfunction. My Cursor randomly jumps to the top of the screen, which is extremely annoying when I am playing. On google I found many people who had the same problem. All drivers of mine are up to date. Windows has not a solution to this problem.
To be forced to change the operating system to a flawed one is ******* bad.
With such a major flaw I do not benefit from this operating system, no matter how fast it is.
As soon as there is a working, new operating system I will gladly change to that one. (Windows X)
Hate to break it to you but this is strictly a driver issue and up to the mouse manufacturer to come up with a fix. I have a logitech, microsoft and gearhead that work perfectly on 8. Got a cheap knockoff and it displayed the behavior you mentioned.
I switched to the built in drivers and the problem went away.
