I recently downloaded FSX (standard) onto my new computer. Acurious thing happens. My cockpit panel shows thru to the ground. In essence, I have two views - the panel and the environmnent beyond the plane. Does this on all my planes - stock and freeware. Virtual cockpit remains unchanged. Didn't happen on my old computer.
HP Phenom II 130f

Go to the Settings section and click the Aircraft tab. Here, you should see a slider that says 2D Panel Transparency. Slide this all the way to 0%. This way, the 2D Panel won't be transparent, and you won't see the environment beyond the panel anymore.
Hope this helped! 😀
