Black information boxes on certain icons/links all over chrome

I’ve started noticing black boxes with text on them popping up on various places throughout my screen. They sometimes look a little different but all of them dissapear when I try to screenshot, so it’s hard to show. They also appear when I hover my cursor on my shelf, side panel,etc. How can I disable or block it, it’s causing lots of sensory issues and nothing i’m doing including trying to block hover text is working. I’m on the latest version of chrome OS.
