[osg-users] osgViewer/Renderer ctor set wrong defaults for SceneView

[Robert Osfield]

Hi Christian,

I can't figure out exactly what change you are talking about, could
you have a look at the the github page to figure out the commit that
is relevant.

Also could you explain the problems you are seeing in your
application, which version of the OSG worked, which ones now fail.

Thanks,
Robert.
