Dear Maintainer,
Whenever I ask open-invaders to not do full-screen, instead of the
game going for a lower resolution, my whole desktop has a lower
resolution. This is the output that comes on the CLI when trying to
put the options of game to a windowed mode (instead of the default
full-screen).

~$ open-invaders
/usr/share
