The whole linux graphics system is moving from X11 to Wayland, and there isn’t any unified way to write a mouse-chasing widget like this one. You can do it in X (but compositing it is a nightmare). Wayland doesn’t tell you where the cursor is if it’s outside your window, and doesn’t have an API to ask. You could probably manage it as a Gnome extension and KDE Plasma thingy(?). The Gnome extension interface just changed out its entire javascript (yeah, fricking javascript) engine, so you have to write this one twice just for one half of the ecosystem. And that doesn’t cover the Steam Deck yet.
