This doesn't seem to explain how it would happen after plugging in a new keyboard, or trying to use the on-screen keyboard, though...

  Same generic keyboard debouncing in use in all 3 instances on the windows end? I know windows drivers debounce mouse clicks because I had a really old mouse that would double and triple click by accident on Linux but not in windows. I might be wrong, but changing the device might not affect it if the different devices are handled by shared runtime code

    Sounds like a reasonable explanation for physical keyboards—if the new keyboard used by the OP was identical to the keyboard on their machine, I can see how Windows might reuse the same device driver instance since it has already been loaded into memory. But what about the on-screen keyboard? Do on-screen key presses get routed through the keyboard device driver too?

      So fingers bounce when they touch a screen? I wrote a capacitive touch driver once back in uni and we debounced that. I don’t know how windows does it, I’m speculating

        It wouldn't be the same debouncer, keyboard input is usually debounced before it reaches the OS, let alone whatever windowing system that an on screen keyboard sends events to.
