I don't know witthout testing your specific shader and scene graph setup.

For your own work, if you can't switching completely to GL3 why not
just use standard OSG build and not bother with the aliasing.  For
decent GL drivers you should get access to modern GL features via the
OSG extension system, you don't need to go explicitly enabling GL3/GL4
features. the only exception is OSX and their CL3 core profile mess.

Robert.
