Disable Factorio GUI info tooltip

What Factorio mod or setting do I need to turn off to prevent this tooltip from displaying? I can’t figure out how I turned it on and it’s interfering with my game.

I have many mods loaded and it takes many minutes to restart every time, so the process of figuring out which mod it might be is laborious. I’ve searched the internet for keywords that might guide me, and have come up short.
