Nevermind, there are other reproducers. Case 2 from the IEEE 2010 Vis contest data has a CT scan in it, and I can reproduce it with that data; plus I must have created that UVF recently, so it's probably not a "really old UVF" issue.
Also reproducible with an old data set from a collaborator... potentially every data set that has multiple resolutions?
