HI Gianni, My guess would be that you've introduced a threading bug by creating/destroying state objects in the scene graph whilst it's being rendered.
If you want to toggle on/off behavior like this considering using a NodeMask on the wireframe portion of the subgraph and just toggle the wireframe version on/off as required by sett the Node::setNodeMask() to 0x and 0xffffffff to switch it off/on respectively. If you do want to create/destroy state then just make sure you are using a ref_ptr<> to any objects you want to keep around and reuse a C pointer will just end up a dangling pointer when your remove the object it's pointing to from the scene graph.
