I quickly looked into this using the experimental state of the mxnMultiWidget but I get a Workbench crash. This might be unrelated so I tested something else:
I used the StdMultiWidget, loaded Pic3D but then I used the Render Window Manager to change the Mapper of the axial render window from 2D Mapper to 3D Mapper.
I get the following crash:

floca added a comment to T28801: [MultiLabel Segmentation][Utilities] Exception thrown when converting to MultiLabel.

Should not be address directly now. Reason: With the new Segementation class, there will be a hard upper limit for the number of labels anyways. In this corner case we also would have to show a error message then, just telling that we cannot cover more then 2^16 labels. So that the provided image cannot be converted into a label image.

isensee added a comment to T29292: Unsupported pixel types.

Stefan is right that, from the medical perspective, there is no need for these pixel types. And urgently needed not they are. We can easily convert all the files with strange pixel types to files with 'normal' ones. The issue here is simply from a usability/user experience perspective. It is uncommon to me (and probably other as well) to load an image and then get told the pixel type is not supported

Not supporting some pixel types can be very frustrating for users, so it might make sense to extend this list (I would certainly appreciate it and a 200MB standalone is really not large by 2022 standards so there is some headroom imo ;-) ). This is not the first time I ran into this issue :-/

kislinsk added a comment to T27578: 2021.1 Linux installer does not work on Fedora.

Looking closer into the issue I wonder why it should not work without TCP Wrappers. It is an optional dependency of DCMTK which, regarding to storescp, adds two access control cmd-line arguments that we are not using anyway as far as I can see. So maybe it is just an issue since we so an explicit requirement check and then of course DO link against it. If we would explicitly disable it in DCMTK and remove the check in our CMake script, it should probably work already,
