The Wayland spec doesn’t allow for clients to arbitrarily get clipboard data under typical conditions. Since most applications these days are running under Wayland, it should be that copying to the clipboard isn’t exposed to X11 clients most of the time (only when copying from or pasting into XWayland).
I understood that all X11 apps running under Wayland are running inside the same environment, or is that wrong?
In other words, all X11 clipboards are shared.
I’m also not sure about clipboard isolation, since I’d have thought that copy/paste between Wayland and X11 would be expected.
