Hi Robert, et al,
we're having an issue caused by this changeset:
http://www.openscenegraph.org/projects/osg/changeset/12303
Particularly the change in parsing "GL_SHADING_LANGUAGE_VERSION" broke
certain GL/shader features on many systems (all our clouds are gone with
osg >= r12303).
Cross-posting from our devel-list:

Thanks to Csaba for debugging into this issue.
I also see the issue on my system.
So, obviously the new code for parsing the GL version strings doesn't
work for all systems. Could you please have a look?
cheers,
Thorsten
