Geometry iluminated with lumen changing shadow map as camera approaches (ilumination source is a self-iluminated plane)

Hello everyone! Newbie query here

I´m messing around with lumen, and found that iluminating my scenes with softboxes creates a beautiful realistic lighting, but on the other hand, produces a series of artifacts when the camera approaches, as shown in the gif bellow

I would like to know if anyone knows a way around this issue!
