"What's your setup like?"Currently I'm using an old, slow laptop, with a graphics card integrated in to the motherboard. Nothing special. But I don't do any demanding graphics processing on it. I just watch movies and use web browsers and a terminal. I don't play graphically intense games on it.

I don't see why this should concern me or 90% of X users, because if any malware manages to run on our systems it'll already have full control over them without needing to resort to any kind of keystroke sniffing in X.
I'm struggling to think of a scenario where malware's running on the same machine with access to a single X session, which doesn't already have full control over the account whose keystrokes they'd be presumably sniffing. They could just substitute their own malware versions of web browsers, shells, editors, or whatever other software the user uses and sniff keystrokes in there, without needing to touch X.
Not that it hurts to have more isolation than you get in X, but I'd need a lot more convincing for me to give up the convenience I already enjoy with X.
Can someone paint me a realistic, relatively common threat scenario where not having Wayland's isolation would actually present a serious security risk?
