I have similar problem. When I turn on screen, touchscreen becomes unresponsive. It starts working after a few minutes, but it happens every time screen turns off and on.
I tried pc companion software repar, reinstall software, start in safe mode, removing apps,
but none of these solved my problem.
I will send it to technical service, but it looks like a software issue. There must be an update to fix this.

I did the same thing as you but still cant get rid of the ghost touch after unlock the phone. The ghost seems to be constant at top right notification bar and can be reveal through Developer options > Show taps
