Capture the gamepads even when the window is not focused. Note: In theory, with this flag set, we could capture gamepad events even without a window (--no-window). In practice, scrcpy still requires a window, because --no-window implies --no-control, and the input manager is owned by the sc_screen instance, which does not exist if there is no window. Supporting this use case would require a lot of refactors.
