I believe that this is just an issue that will stay with you, if a factory reset does not fix it. I experience the same problems as you, but only when charging. My solution is to unplug, turn off the screen and turn it on again. Sorry I can’t offer a permanent solution, but I am dealing with the same problem as well. One more thing, if I charge using a portable battery pack, it sometimes gets rid of the issue and does not trigger the screen to go nuts.
