My mouse cursor jumps two spots that activate without touching and the mouse moves to these spots. One is at the very top of the screen and the other is about 2 inches below the first. At times I can see the cursor jump between the two spots. Using the touch pad I move the cursor back and shortly after I it will move it back. Wiping the screen with a cloth wil sometimes stop the movement but after 20 to 30 min it will come back. I have rebooted the system and it will still do it. It is always the same 2 spots on the screen. I have updated the synaptic driver, the graphics driver, hid touch screen driver, and the display addaptor driver. Each one seemed to fix the problem for a short time then it would come back. 2 years ago I had the same problem and I found a post that said to disable something in the mouse settings but I can't find it again. I see lots of post with this problem but no solutions that last more than a day or two and the issue comew back. it ad not been a problem for me in a while until I updated the display driver trying to get my screen brightness keys to function and then it came back.
Thanks
