When creating a cube with a different texture on each side, the last created side of the cube shows on top of the others. No matter which side is facing towards the user.
The problem only occurs when running in fullscreen.
The code used is shown below by sthorsen.
Thanks in advance tiels.

You’ve got no depth buffer. Speicifically:
Window.create(title, 32, 0, 0, 0);
should read
Window.create(title, 32, 0, 16, 0);

Thank you very much! (from tiels as well)
