For the past few days, my Moto X has had a very weird display problem - every minute or so, it briefly (like .25 second) goes black, then recovers. It happens both on the home screen and when any app is running. Changing the brightness settings, as I've seen suggested elsewhere, doesn't help. It happens in safe mode as well, which tells me it's a hardware or OS (non-rooted) issue I am NOT interested in doing a hard reset, so nobody even suggest it (I've never seen that help any issue on any of my previous phones anyway). Any other Moto X owners seen this behaviour?
