I'm referring to the actual clipboard on your PC, yes.

Don't get me wrong ofc X is not without issues at all, but Wayland is like chopping off your arm at the elbow because you messed up some nail polish, and you arguing for it is like saying that now since you don't have that arm anymore no one can break it, while all the other OSes watch on in horror and embarrassment as they allow all access to screen elements to any random app like god intended.

If you got malware installed it's all over anyway. Why bother with weird screen access when you can just ransom the home partition and all personal files instead?

Without OBS, Discord, Steam, Guake, proper screenshot tools, etc. it's not really a functional OS anymore for general use and that's what you get with Wayland.

If Wayland fixes all the issues with it I'd happily switch, but it likely won't since they are fundamental to it's design and if so then the only way it will secure Linux desktops is by making no one ever use one again.
