I tested on an older laptop with Intel graphics, and it works, reporting as version 2.1. Linux works and is using GL 3.0. I'm wondering if 3.1 is what the problem is.

Re: [osg-users] osglight demo problems with Intel graphics on Windows
Hi Ryan, The osglight example just just the fixed function pipeline and doesn't provide any shaders. What you describe sounds like an Intel driver bug. The best thing you can do is check for latest Intel drivers. Robert. On Mon, 9 Jul 2018 at 21:51, Ryan Thoryk wrote: > > I recently started a project based on the osglight demo.

[osg-users] osglight demo problems with Intel graphics on Windows
I recently started a project based on the osglight demo. I have a laptop with switchable graphics, and under Linux the demo works great under both Intel and Nvidia graphics. Under Windows 10 however, lighting doesn't appear to work with the Intel driver, even though it works fine in Linux (bad drivers?). The console also outputs this: > > Screen 0: > Vendor: Intel > Renderer: Intel(R) HD Graphics 3000 > GL Version: 3.1.0 - Build 9.17.10.4459 > Warning: detected OpenGL error 'invalid enumerant' at After Renderer::compile > which implies that the app is using shaders. I thought that the OSG lights used the FFP OpenGL lights and not shaders. I'm attaching a screenshot of the project.
