    Description

      wip/runtime2:

      Scaling an object by clicking on it and dragging with scale tool active sometimes crashes.

      To repro, activate the scale tool, click and hold mouse button down on the object and drag back and forth so that object scales between negative and positive scaling. A couple of seconds is usually enough to cause a crash when decomposing the matrix. All matrix values are NaN.
