Picking when using both 2D and 3D actors reverses all faces/render order.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Using either Annotation/Tcl/labeledMesh.tcl or Annotation/Python/labeledMesh.py, rotate the sphere, then pick using the 'p'-key, anywhere. This will reverse all faces of the sphere.
In a more elaborate example with several 3D-actors, all actors will be rendered in reverse direction, making far away actors overlap close ones.
This has been tested on Debian SID/Unstable with packages vtk-examples, vtk-tcl, python-vtk and libvtk4, all having version 4.2.6-1.
