you should always use the gaussian filter for unclamped images. all those sharpen filters
have a spot where the curve is going under zero and cause negative pixelvalues, surrounding areas
with a lot of light. that´s the black borders around your windows and lights

I used Mitchell filtering, I like the sharpness. But it could be that's
causing some problems with the high contrast areas in this render.
