I don't think it is an issue of the osg itself. Please search the mailing list/forum for similar questions about this. It has to do with windows display scaling.

Hth, regards

Image 1 shows a aircraft and a cow rendered by OSG. I just loaded the two nodes with a osg::Group object (see the code listed below). But the viewer did not situated them to the center of viewport.  I think this is a system compatible problem because the situation is  the same when I run the osgviewer.exe of OSG.

> image 2 is an example from Freesouth. It shows how to combine the OSG with MFC (I packed the source code in attachment).  When I run it I found that the View was “broken” and the edge of view was dithering.
