I have surface 2 which is running windows 8.1 RT. The device has a very small crack in the glass in upper right corner. LCD is ok and everything is fine, but from time to time I get a ghost touch where the crack is, and when this happens, it could be quite annoying because the surface thinks that I am touching the screen with two fingers instead of one, you can imagine how usable the tablet is when this happens.

So, is there any possible software solution to my problem? Could the drivers be modified to partly disable touch, only on that area? Or maybe to somehow tell windows to ignore touch if it's for more than two seconds?

Any ideas?
