Does anyone know which add on has the White Square target when fighting?

It looks to lock around targets in a square outline with 4 white triangles at each corner.

The red highlight is difficult to see sometimes, so this would be helpful.

Found a video showing it:

This isn't an add-on. Whilst targeting a mob, hit tab and the box should pop-up. It's priority targeting, but if the mob is off screen/not in FOV, priority is now whatever is in front of you.

Thanks, I will try.
