Hi Serge,
The behaviour of the problem sounds a bit like contextID's aren't be
managed correctly. osgViewer/GraphicsContext should be managing the
contextID automatically for you. It would be worth double checking by
looking each windows ContextID i.e.
gc->getState()->getContextID();
You should 0 and 1 respectively for the two windows.
The other possibility might be that your own custom graphics code does
manage multiple graphics contexts properly so tries to reuse texture
objects or display lists from the wrong graphics context.
Robert.
