Strange DOF light (visible DOF from lights that are invisible to camera)

Hey,

I’ve encountered a strange problem - when I was testing something I’ve noticed that I can see a bokeh from the light that are invisible to camera. Test scene is quite simple - a plane and instanced lights above it, camera below it. You can see the bokeh from lights and it is distorted, as if part of it was cut (top part in front of focus point and bottom part farther away from the focus point).

Why does it behave like that, is that a bug? It certainly looks like a bug.

Thanks,
Kuba

Hi,

Sorry for the delay.

I was able to reproduce this and this is surely not expected.
This is reported now. Thanks.

Thanks! :smiley: Fingers crossed as it can produce strange effects if real scenes!
