Gateway is a special case since it connects two systems and on Wayland it uses the scaling of the “server” system rather than the host. This is a pretty unique class of issue, at least in my experience. To be honest, I’m not even sure if it works correctly on X11.
Middle English is certainly difficult to understand, but most words still bear some resemblance to modern English. I think it would probably be more like a native German speaker trying to understand a heavy Bavarian dialect, or at worst a Dutch speaker trying to understand the same.
