Weird lighting issues

Hello, I’ve been trying to solve this issue but nothing seems to work, it seems the draw distance for my light effects and shadows is very short or something. My settings are set to Ultra and my directional light has ticked the Distance Field Shadows.
As seen in the picture below, there should only be light entering from the windows but this only happens when I get close, but then the other side of the room gets this problems causing a kind of jitter.
