The line mat has 3 main toggles under the pages Line, Point, and Vector.
When Draw lines, Draw Points, and Draw Vectors are all off at the same time, I get a weird bug where some other object, moves / swaps to another object’s transform in the render top.

I’ve set up the bug to be immediately apparent via the animated toggles in the attached file.
