While fixing a problem with a Wayland app I noticed that the programm got a notification from a Wayland fd whenever I selected some text in any other window (not belonging to the app) and was able to read the contents of the selection.

As I’m not a fan of sharing data without explicit actions (so Ctrl+C, Ctrl+V), is there a way to disable this behaviour of Wayland?
