yes, I did not look closely at the code that manipulates viewports and
adds decorators. However, I've noticed that you set
stage->setCamera(vp0->getCamera()); before creating any decorators. The
view that is rendered into the FBO is determined by the stage's camera,
so it probably should be one of the decorators.
You also don't necessarily need the stage_viewport, just adding the
stage to the scene is enough and the view it renders into the FBO is
independent of any viewports on the main window.

yes, I thought that you'd not have that problem in your real application
or could relatively easily work around it.

the example would be much appreciated. Walking up the parent hierarchy
should work fine for that.

cloning, instead of sharing, the cameras from the main window and
avoiding the buffer swap should help avoid that.
