[Qt-interest] QGLFrameBufferObject and multiple threads

Hi again.

1. I am still curious about making QtOpenGL reentrant :)

2. Another question, maybe not worth starting a new thread:

I tried your model-viewer app (
http://labs.trolltech.com/blogs/2008/06/27/accelerate-your-widgets-with-opengl)
that uses QtOpenGL and QGraphicsScene with Qt4.6TP1 and here are my
observations:
- simply had to add to the check QPaintEngine::OpenGL2 as supported engine.
- the graphicsscene-embedded QDialogs no longer show title bars.
- the mesh is rendered in an awkward way, with faces drawn that should not
be.

Did you update the source code of that app somewhere since your blog entry?
What can be done to solve these issues?
Thanks
