Comment 1 for bug 1186714

CatKiller, why do you think that this is the case ?

You can disable global OpenGL Lighting in the OpenGL plugin... it *should* work and trigger this code:

void
GLScreen::setLighting (bool lighting)
{
    #ifndef USE_GLES
    if (priv->lighting != lighting)
    {
 if (!priv->optionGetLighting ())
     lighting = false;

 if (lighting)
 {
     glEnable (GL_COLOR_MATERIAL);
     glEnable (GL_LIGHTING);
 }
 else
 {
     glDisable (GL_COLOR_MATERIAL);
     glDisable (GL_LIGHTING);
 }

 priv->lighting = lighting;

 setTexEnvMode (GL_REPLACE);
    }
    #endif
}

The only plugin that sets GL_LIGHTING by itself is Gears. Do you have Gears enabled ?

Btw, CatKiller, the experimental version you are using is not trunk Compiz, hope you are aware of that...
