I turned this Vertex Highlighter on a few days ago because I thought it would be useful, but now it is in the way and very distracting and I completely forgot where option setting was. I have been looking through every project and editor setting menu and I simply cant find where to turn this off.
Ok, I finally found it. For anyone wondering, it is in the viewport’s “show” flags, under the advanced submenu, labeled “Large Vertices”
