I can confirm that I had the same problem with my new X1 Yoga. It didnt start off this way, but within the first few weeks it would arbitrarily develop the described flickering mouse symptoms. Internal trackpoint, trackpad, and external bluetooth mouse showed the same symptoms. Disabling/re-enabling mouse/bluetooth drivers didn't seem to do anything. Very, very, annoying.
While I'm not sure I understand, I followed the hint of a previous poster and changed the video resolution. The flicker disappeared! When I changed it back, the flicker returned. Ah ha!
I checked for a graphics driver update and sure enough, there was one available and my mouse is currently flicker-free at the highest screen resolution.
