Image corrupted after denosing

[18322119@qq.com]

I am using vray next to render scenes with pure color. I found after denosing, the image was corrupted. I've tried to use jpg/png/tga, but all the types with desnosing brings image corruption.

Attached is an example of corrupt image. You can find some stripes from the left image.

mode=1;
progressive_update=10;

engine=0;
use_gpu=0;
name="VRayDenoiser";
enableDeepOutput=1;
preset=1;
type=0;
radius=10;
enabled=1;
}
