I just checked for this bug, and it works fine. Maybe you're playing Update #13 and not Update #13.1? I'm not sure what are you talking about. Can you send a video or gif?
Ok, I'll try to fix it.
The first one is in the window mode and a lot tineer than the other window ,wich is then nearly in the Fullscreen-mode (after switching)
And yes I play version 13.1
