PxTransform: inverse-transforming broken?

Has anyone else noticed this with the current SDK version? Inverse-transforming a tranlation-vector with a PxTransform seems to produce a slightly misplaced result. It doesn’t happen with “normal” transforming, just inverse.

Try repeatedly transforming and inverse-transforming a vector. Unless I am missing something, you should observe how the vector is not staying in place, but instead drifting away from its original coordinates.

In my program, I have to convert PxTransforms to rotation/translation-matrices in order to avoid this drifting.
