light leaking through corners

[irmin]

Guys, on the pic you can see that the ceiling and the wall have strange closing...
I tried a lot of different things (I don't think it is because of min and max rate are too low, -3 and 0).
the walls and ceiling are in a basic SU color (color 000), the rest af the materials aren't definite yet (except 2sided material)

what is the reason for this? and what can I do to get rid of it?

thx,
irmin
