Touchscreen doesn't recognize touch until I swipe it for 2-3 seconds

Touchscreen doesn't recognize touch until I swipe it for a couple of seconds. Pixel 2 XL.

Used the phone with greasy hands outdoors and rinsed with water a bit before that happened.

The screen was replaced once a long time ago.

Tried: cleaning the screen, rebooting many times.

You can see it on video: https://youtu.be/IZrwbtUo7jo

What sould I do to fix it?
