- Load Image Pic3D.nrrd
- Create new label in segmentation View.
- Click the Region Growing 3D Tool.
- Select a seed point and click on "Run Segmentation".
- The previewed image is very dark.
From what I can see, the level window is reset to its original state after pressing "Confirm Segmentation". The darkening / changed level window is only temporary to help adjusting the parameters of the region growing. To me this seems like a feature, not a bug. At least it is by design, anyway.
