Having a clipping region defined in Solid Viewport Shading and going to Material Preview or Rendered will leave verts outside the previously defined region unselectable [but visible].

There are a few areas in the tooling (select, projection painting) that still needs to be tackled after this patch.

@Jeroen Bakker (jbakker), @Clément Foucault (fclem): not sure this is accepted as Bug then?

I would accept it as a bug as noted in the patch there are areas mentioned that still needed to be updated.
