This is probably because the event handler in vtkRenderWindowInteractor
and the one in Gtk aren't cooperating with one another.  There is a
special vtkXRenderWindowTclInteractor that cooperates with Tk, so
I'm guessing that if you wanted to use an Interactor with Gtk you
would need a special vtkXRenderWindowGtkInteractor.   My advice
would be to do all the event handling (including the redraws) through
Gtk, and not use the Interactor at all.
