Render selected blurs picture around this object

[Bormax]

Hi
I use Corona 1.3 and have issue with Render selected feature. If it's active it makes picture around selected object more and more blurry every time I start render. If I use IR it blurs picture more every time IR re render selected object.
Please check the attached pictures - here I just start and stop render selected wide green box several times, and if you look on gif-file you can see how it looks with IR.
All settings here left by default.
I didn't have this problem using Corona 1.2 with daily builds
