[osg-users] Compiling vertext shader fails on Intel

[Chris Hanson]

I think compiling the shader is deferred until it's actually needed.

The fact that it doesn't list WHAT extension it needs suggests to me that
the driver is just broken and there may not be anything you can do.

You could try a validator and see if it flags anything wrong with your GLSL
code: https://github.com/KhronosGroup/glslang
