When it was having problems, did you try rebooting at that time? If not, it just may be the fact that you actually had to reboot the phone with the system update.
When I have the problem I hold the power button till a reboot is forced, phone boots fine and issue is resolved (till it happens again) so seems to be a software problem.
Problem is linked to both the screen and the digitizer as the phone vibrates recognising random phantom screen touches while the screen has noise, lines, blocks of random pixels and negative images.
Have recently (just now) forced the phone to disable HW overlays, we'll see what happens...
