Black line flashes on my screen randomly while I am moving objects or Camera

Question

So, I have a camera3D that I rotate around a box. However, while rotating there is a black line that will flash every now and then. It isn’t on the box, and it also happened when I rotated the box. Does anyone know why this is happening?

Show us a video of this happening and any code snippet that is manipulating the camera so that we can investigate.

Unfortunately it doesn’t seem to appear (or at least I’ve had no luck making it appear) while using my screen capture overlay… weird.
