I've tried to erase noise of some photos and noticed a strange behavior. I did the following:
1. Open a Photo
2. Use Filter -> Noise -> Noise Reduction (I'm using the German version, hope it's called that way)
3. Set Luminance Noise to Extrem, and take the slider to a high setting. Everything else is set to default.
What I got before rendering, just seeing the preview in the main window is what you can see in Preview.png.
What I got after rendering you can see in Render.png.
Render looks much worse to me. Is this meant to be or might this be a bug?
Thanks for your help.
