I tried the trace here w/ NVIDIA GL driver and the rendering here looks just
like your screenshot.

I though by artefacts you meant the countours in the balls, but I'm not sure
anymore. Could you describe exactly what you believe to be artifacts?

Also, glretrace here shows many errors, both with NVIDIA or Mesa:

Mesa:

Mesa: User error: GL_INVALID_VALUE in glMaterial(invalid shininess: 1000.000000
out range [0, 128.000000])
38030: glDebugOutputCallback: High severity API error 0, GL_INVALID_VALUE in
glMaterial(invalid shininess: 1000.000000 out range [0, 128.000000])
0 38030 glCallList(list = 1)

NVIDIA:

38030: glDebugOutputCallback: High severity API error 1281, GL_INVALID_VALUE
error generated.
0 38030 glCallList(list = 1)
38030: warning: glGetError(glCallList) = GL_INVALID_VALUE


I suspect this may be an application bug... Maybe induced by something in Mesa
drivers, but it looks like the drivers are rendering what they are being told..
