Any flicker is due to broken clipping.  Reparenting is easy:

        while (line->_parent && static_cast<KstViewObject*>(line->_parent) != 
static_cast<KstViewObject*>(this)&& !line->_parent->geometry().contains(line->from())) 
{
          KstViewObjectPtr p = static_cast<KstViewObject*>(line->_parent);
          line->detach();
          p->_parent->appendChild(line.data());
        }
