Enable windowed mode and raw input to get all inputs on virtual display

This fixes an issue where the game does not receive most of the inputs
sent to the virtual display. It is not really clear why this change is
necessary, something related to the game or the X server must have
changed recently...

Note: Fixed some formatting along the way.
