3D editor gizmo; Other 3D improvements; Bug fixes.
That doesn't happen for me - if you run in to a problem please file an issue following all the guidelines, as typically we need all that information to be able to investigate.
I tried it in a new project with multiple objects - the bug consist. Import a 3d model and pull the Z-Gizmo. Its the RED wireframe bounding box (check "show the bounding box" in the "3D model editor properties") that moves to fast, not the cyan box.
