[Qt-interest] Flickering during redraw of OpenGL viewport backed QGraphicsView

[John Clayton]

Hi All
Has anyone else experienced flickering of the drawing surface of an open-gl
backed QGraphicsView?  I can't seem to work out why the flickering occurs,
pics of it in action are here:

Any help or direction appreciated.  I wondered if I needed to set some
window (or GLWidget) attributes to stop it flickering, not sure tho.


Thanks,
