Digitizer dead spot topic

Hi folks,
I'm having some screen issues.

There is a vertical band on the right side of the screen that isn't registering any touch input. I'm currently running CM 12, but I've tried installing a stock variant and the problem persists.

This all points to a bad digitizer, but the affected part of the screen seems to work fine in recovery and on the lock screen.

I'm completely stumped. Does anyone have any advice?
