Top part of my touchscreen is not working

Moto C plus | Android 7 | Rooted

Suddenly top part doesn’t work. In the test, if I keep on moving in the white area, evetually, one random one will turn green. Also a few minutes before, it was only one white row. I didn’t drop the phone or get water in it when this started.

Any idea what it could be and how I can fix it?
