I extended the sample above and tried to reproduce
the problem I actually see. I now use StereoDecorators
and ShadowMapViewports. I removed the reinitializeAllGLObjects
method and replaced it with something like this:
PassiveWindowPtr mPwinNew = PassiveWindow::create();
PassiveWindowPtr oldWin = mPwin;
// copy all viewports
for( unsigned int i = 0; i < mPwin->getPort().size(); ++i )
mPwinNew->addPort( mPwin->getPort()[i] );
mPwin = mPwinNew;
mMgr->setWindow(mPwin);
mPwin->init();
mPwin->activate();
mPwin->frameInit();
subRefCP(oldWin);
Essentially, I replace the PassiveWindow with a new one.
That fixes the bug you could see in the example I posted
in reply to this mail.
Now I added StereoViewports with shadows. When I switch
into stereo mode I create the viewports and add them
to the window. Here's the (correct) result:

Here's what happens if I switch back to mono and
again to stereo:

Somehow the diffuse light got screwed.
This does not happen if I _recreate_ the stereoviewports
everytime I switch into stereo mode.
I just have no idea what is happening...
here's the new sample code:
