The light in your picture#2 is extremely bright compared to the others.
(through the bloom and dof you can't even see the actual shape of the light as it is in the texture)

The brighter a part in the image is, the clearer the blur-shape is visible, just like here:

The bokeh-dof and hdr rendering in the game does exactly the same, so I honestly don't see that this is a problem...

Maybe it's just because it's a still image, I dont know, but it seems perfectly normal to me.
(you can see the light's brightness better in the actual game)
