  and after reading in the second volume changes to

  • VTK/OpenGL2 - Packages are available here.
    • Issues should be reported on the slicer bug tracker selecting `Rendering` category
    • A screenshot illustrating the issue showing both version of Slicer (with / without the new backend) should be attached
    • Step by step details explaining how to reproduce the problem
  • Light weight viewer
    • The recommended approach is to integrate the layout manager and regisering a custom layout
