Effect different depending on computer

Something is causing the effect to render incorrectly on the laptop.
There are 5 difference in the GL info dialogue box - these capabilities are in the laptop list but missing from the desktop:
GL_NV_clip_space_w_scaling
GL_NV_conservative_raster_pre_snap_triangles
GL_NV_shader_atomic_float64
GL_NV_texgen_reflection
GL_NVX_blend_equation_advanced_multi_draw_buffers
Given that these are missing on the desktop but the desktop seems to be rendering correctly, I doubt that this difference is important.
I have suspicions that other effects may also be rendering incorrectly on the laptop though I have more work to do to identify any. I'd be grateful if others could test this particular ISF to see
a) if my desktop actually is correct and hence my laptop wrong and,
b) if someone has a similar setup to me if they experience similar issues and,
c) can anyone think of something (obvious) I've missed and,
d) if anyone has noticed any similar rendering differences (say between GPUs or Mac/Win etc.).
Perhaps OpenGL is so complicated that I cannot hope to have an identical environment between two computers - I hope not.
