Issue description

The lights start swimming along, typically when you reach the limit of lights you can render.

Another issue is that Light culling seems to be broken, as is evident given that you can look on a large object with 9 lights, and if you're in a position where only a few lights are in the view frustum it will still be trying to render the lights that should have been culled (on the vulkan renderers this works properly, and it is possible the issue above is related to this culling problem)

I remember the Mobile renderer had practically the same issue a while back

Steps to reproduce

Move the camera around and observe what's happening on the Plane
