You may be requesting a depth buffer format that is not supported by the graphics card

What if your lines are being treated as 2D objects... this could be bad. If it only affects some PC''s then perhaps those graphics cards simply do not recognise that the lines are 3D and simply assign an x/y to them without a depth. If so your only option would be to transform and sort the lines yourself...

Just an idea.
