Hi,

in my program i have a widget derived from QGraphicsView and have to
switch between few scenes with QGraphicsView::setScene(myNextScene).
It's also possible to have myNextScene=0, so one sees then the background
color of QGraphicsView's viewport.

The problem is that if I set the viewport to QGLWidget and myNextScene=0
GraphicsView background gets not updated and stays corrupted or maybe better
to say will not be cleared.

Alas, i have no experience with OpenGL.
Could someone point me in the right direction?

Thanks in advance,
Albert
