Apple support has a very similar issue that has NOT been resolved either.
Remedy response on Apple' Support Blog stated the following solutions that did not work.
Hard Reset Remedy
Charging issue possibly
Total backup and reset the iPhone Remedy
No solution found
My issue is after my iPhone 5 phone rest awhile charging; when I first cut on my phone the digi screen issues occur.
screen starts zooming out/in with one finger touching.
Touch the digi screen anywhere and the screen can jump clear to other side of the screen.
Selects other screen options that where not selected by user.
Jumps around spastically like a muscle jumps in the body without cause.
I'm roughly an hour from the nearest apple store so i may take my iPhone 5 to them
If no resolve or update is found by Saturday.
