Mouse coordinates issues with boot and window change

[Mimigris]

• When booting a game, if you do not move your mouse at all and that the mouse coordinates get tracked, the coordinates value returned will be 0, 0 instead of the correct mouse coordinate
• When changing the window of the game from window to fullscreen, the mouse coordinates gets updated based the size of the fullscreen window rather than the window of the game, resulting in an inacurrate answer (e.g. on a 1920x1080 screen, putting the cursor in the bottom-right corner while in window mode, then switching to fullscreen will return a value 1919, 1079 for the mouse coordinate)

• Fullscreen -> window also returns an incorrect value
• Switching between window and fullscreen moves the coordinate of the mouse on the screen in a way that does not match with the window of the game
