On a Dell Latitude xt2 tablet I have noticed that after a few minutes the mouse position will jump to the bottom right hand corner of the desktop.
I had a bunch of issues and weirdness with the mouse jumping around and phantom clicks happening and I disabled some of the pen and touch input settings and it seems much more like a normal laptop now. However I can't find any setting that returns the mouse pointer to a certain position.
I just saw it happen while I was typing this. There is a bit of a screen flash and then the mouse pointer jumps to the bottom right hand corner.
If anyone knows how to disable this behavior please let me know.
