Recently I update Slicer from 5.8.1 to 5.10.0, and I found that sometimes the scissors in Segment Editor took very long computing time. After several small experiments, I found if the trajectory of the scissors is “outside“ the segment region and draw the trajectory slowly, this delay will happen. But this problem won’t happen in Slier 5.8.1 in the same condition (same segmentation nrrd, same “outside“ and “slow” trajectory).
Sometimes I want to cut segments carefully so I slow my drawing speed, and the computation may take several minutes to finish just one cutting.
