Hey Ed Burgress,
I’m not sure if you are aware of the fact that the reproduction steps I provided aren’t the only case where this happens. The effect is insanely visible when the movement of an object nears 0, either due to distance or due to having the same speed as the camera.
This is only one of three rendering issues I’ve encountered. Second one is Bloom not behaving as expected when the object is on the edge of the screen/viewport. Third one is with the smaller Lens Flares which do not fade out like the larger ones do.
