This code has been written in java. I'd like to know if i'm missing anything here, because in the fixed time step update loop, if i display for example a window, and move the window around, the framerate will sometimes change until i stop moving the window around, which is kind of confusing to me. Is that normal? Or perhaps I might be missing something Guidance will be appreciated
