Hi Paul, Yesterday I spotted OpenGL warning being generated by the OSG when running shaders, and traced it back to an addition that Mike made for the geometry shader support. I've added an extra check against geometry shader support before calling these methods and fixed the OpenGL warning. My guess it'll fix the problem your seeing too with shadowmap. This fix is in 2.3.2 and SVN.
Could you update and let me know if you still see this issue? Robert.
