// Just after restoring from the fullscreen mode, the window's size might be a wrong value on Windows.
// This was the cause to invoke SetSize callback unexpectedly. This sounds like a GLFW's issue, but this is not confirmed.
// As the window size should not be changed, setWindowSize doesn't have to be called anyway.
