I am running 8.1 on a desktop and I find the same problem happening every time I open a metro application to the time I shutdown my computer. I have a two monitor set up and when I try to switch between them it will "stick", as in it takes a certain speed to get it to crossover. I am aware other users have had something similar, but I have never seen anyone say that it occurred after the use of an app. I still have not found a fix out there that worked.
