I noticed strange behaviour of noise level reporting in VFB. I set noise level to 7,0 as stopping conditions. Usually it takes 10 passes to reach this level, but for some renders it takes a bit longer and after 10 passes noise level shows 7,2 or so. If i notice that and stop render manually, then VFB shows very small noise level, like 1,5 or so, but if i let it render to 15 passes then after that, noise is shown at about 5%. Not that it bother me much, but i thought i let you know.
