The culprit is probably this change:

> \* Automatically flip left handed volumes when loading into 3D Slicer to make the…m compatible with all algorithms. Fixes flipped normals in segmentation node for left handed volumes.

I should have suspected that it was wrong, because images should only be ever transformed with homogeneous transformation matrices, never with just flipping.
