no, its not new - just most that experience it return it under warranty replacement or repair ..

Considering the fact you've tried multiple ROMs including stock with the same intermittent digitizer issue resulting clearly shows its an issue with the digitizer as all the software is cleared out of the potential for being the problem by the fact you have tried many including stock

its not uncommon for the digitizer to display unstable issues on some units produced - either from the connection to the main board or perhaps a firmware issue, heat issue (other users site heat from leaving on a window-sill for better reception but it cooks in the sunlight), many possible causes

Swap it out at your store or through an insurance claim and start new
