Greetings,
I have run into a strange problem with multiple QGraphicsView-s and OpenGL rendering.
I need to implement an application with multiple QGraphicsView-s (each has it's own scene). I have implemented OpenGL rendering just like in documentation (view.setViewport(new QGLWidget(QGLFormat(QGL::SampleBuffers))) for each view, but now if I use OpenGL rendering in more than one QGraphicsView every one of them shows only black screen (no items are drawn). Is this some kind of a bug, or am I missing something? Please help. Thank you in advance.

Regards,
