Annoying hover pop-ups

Can someone explain how to disable these pop-ups that obscure code and get in the way when I hover on things?

I can see how to disable (most of) them one at a time or by coding language, but that appears to also disable validation, which I want as it shows the colored lines on the right-side bar and I can see as warnings or errors in other places than pop-ups obscuring the code I'm trying to read.
