- Electron version: `0.37.4`
- Operating system: Windows

When I maximize my [frameless](https://github.com/electron/electron/blob/master/docs/api/frameless-window.md) electron window a small part of the window in an unmaximized state is visible on a secondary monitor.

You can visibly see the "line between the monitors" and you can see some really strange overhanging content that is over that line.

**Steps to reproduce**  
1. Open an electron app
2. Maximize the app on your secondary display
3. Look closely for the overflow onto your primary display

This might take a few times to trigger, it appears to do it about 70% of the time :confused: 

atom/browser/native_window_views.cc
return window_->IsMinimized();
}
void NativeWindowViews::SetFullScreen(bool fullscreen) {
  if (!IsFullScreenable())
    return;
#if defined(OS_WIN)
  
  if (fullscreen) {
    last_window_state_ = ui::SHOW_STATE_FULLSCREEN;
    NotifyWindowEnterFullScreen();
  } else {
    last_window_state_ = ui::SHOW_STATE_NORMAL;
    NotifyWindowLeaveFullScreen();
  }
  
  
  if (!thick_frame_) {
    if (fullscreen) {
      restore_bounds_ = GetBounds();
      auto display =
          display::Screen::GetScreen()->GetDisplayNearestPoint(GetPosition());
      SetBounds(display.bounds(), false);
    } else {
      SetBounds(restore_bounds_, false);
    }
    return;
  }
