I felt a lot of cognitive dissonance while reading this article, specifically where it focuses on the things that do no work on Wayland, yet are completely working on my vanilla Debian distro with KDE on Wayland. And, as we all know, Debian (not SID) slants more towards stability rather than being bleeding edge up to date. It's been a very long time, and releases, since I last had issues with copy-paste and screen recording, so I don't know what the author is talking about or maybe, when he's talking about.
