Using the latest Preview version of 3D Slicer (4.13.0 2022-01-19) in the Segment Editor I encountered some weird behaviour in the table of segments.
I had eight (8) segments defined, and I clicked the Threshold tool and scrolled down.
The table entries perpetually flicked between two states, at a frequency of ~once every 3–4 seconds,
My best guess is that there might be two conflicting instructions in the underlying code for the table:
- one saying “a scrollbar needs to be added”,
- the other saying “a scrollbar is not needed”,
I speculate that the problem arises because
- when the scrollbar is present the vertical spacing of the list of segment is compressed, meaning that a scrollbar is not needed; but
- when the scrollbar is not present the vertical spacing of the list of segment is expanded, meaning that a scrollbar is needed.
