>Or is this a bug in JOGL?

It looks like a driver bug. The integrated graphics chipsets from Intel e.g. the "945GM/GMS, 943/940 GML Express Integrated Graphics Controller" and similar models are widely known to have various issues with OpenGL.

I would recommend to upgrade to the latest driver version for ur chipset/graphics card and hope that this resolves the issue.

>So what can I do to make it work on both machines?

Other than that try removing "gl.glDepthFunc(GL2.GL_LEQUAL);" and rely on the default driver value. Maybe explicitly setting the depth value triggers some strange behavior.

If that doesn't help try to fiddle with ur driver settings and try disabling/enabling some stuff an see if that resolves ur issue.
