Hi Morne,
I wonder if the osgShadow technique was trying to use a Pbuffer to
implement the render to texture, this isn't supportable when using
GraphicsWindowEmbedded. However, a crash shouldn't ensue, rather
there should be a fallback to use frame buffer for RTT.
BTW, does your OpenGL diriver support frame buffer objects?
In terms of the moving to QGLWidget and osgVIewer window inheiritance
fixing the the issue, this would indicate that pbuffer might be in
play as this is one of capabilities that it adds.
Robert.
