Title: Render selected blurs background
Post by: sprayer on 2019-12-14, 14:20:50: I was need to render several variations of doors, and used render selected option with unchecked Clear VFB between render, it appear what makes blurred background.
Attached image from the sixth renderings, i marked selected object.

Also sometimes NAN errors appear, i am sure it because of render selected not the scene setup because single full rendering never gives this error.

Interesting artifact, probably has to do with overwriting degradation of the background cache image, but that's my guess.

Anyway reporting this, Thanks.

Post by: romullus on 2021-03-23, 19:56:50: I just stumbled on this bug again. Good thing that it is solvable with the change of filtering type, but it would be nice if it ultimately would be fixed, because i love HQ filter.
