Notice the difference between the X server and the window manager. The X server manages the display (and mouse), redrawing (bits of) the display when the mouse moves, noticing that the mouse has changed window (and probably telling the window manager), redrawing the window as the application (e.g. a full-screen editor) requests, etc. The window manager controls the interaction with the windows, which is on top of which, and so on. It does this by sending commands to the X server, which is the only program that can actually write to the display.
