Hi Sergey, The FLATTEN_STATIC_TRANSFORMS operation is not able to remove the topmost node so can't flatten this MatrixTransform you've added. This limitation is due to the optimization being called with external code holding a pointer/reference to that topmost node. To be able to optimize this topmost node away we'd need to come up with a new API that requires users to replace the pointer references they have.
Without any API changes the way to get round this limitation is to have a Group node as the topmost node, then have the new MatrixTransform as a child of this group, then the original scene graph below the MatrixTransform.
