Is this a glitch? Random lines when spawning an actor

For this specific action, I am setting the “render in main pass” to false in the “child actor” of that car blueprint actor. And then I spawn another actor with the same class as that “child actor” in the players hand. Notice the blue lines on the screen that appear sometimes when I spawn the tire in the players hand.

Is this a rendering glitch? Or is it something I could be doing wrong?

Disable motion blur and temporal AA and see if the problem persists.

Thanks! Disabling motion blur worked.
