Description

Not sure if this is a Slicer issue or a MONAI issue, but I've only hit the issue so far using the MONAILabel and MONAILabel Reviewer plugins. When I use threshold an image and see, for example Editable area = Inside segment_1), after "Apply" the segmentation mask for that label disappears from all 2d views. Any paint etc. drawing done after that point similarly does not appear in the 2d views. I do however see the label in the 3d view (including post-threshold values and any modifications I make with paint etc.).

Research direction

Start by reproducing the issue in the MONAILabel and MONAILabel Reviewer plugins: threshold an image, apply the change, and compare the segmentation in 2D and 3D views. Trace the path that updates the segmentation after histogram thresholding; done means the affected label and subsequent paint edits remain visible in all 2D views.
