I tested too. It started windowed. The image was mostly still; there were sounds of firing going on, but nothing was actually moving or happening - except the planet was rotating. When I Alt-Entered to fullscreen, it started rolling, the ships moving slowly leftwards and shots were coming from the right edge of the screen. Whenever I Alt-Entered back to windowed mode, the ships went still again even though firing sounds were still audible and the planet was rotating, very weird. Also, the firing ship was not visible, though, and did not show up even by the time the other ships disappeared altogether, is that intended? Hahaha, this is funny. I just used Fraps to try and capture the weird behaviour while windowed, and whenever I started recording video the ships would move, and if I stopped, they stopped. Some derivative of Murphy's law applies, I'm sure.
