Gnome Shell under X is totally fine with wmctrl. But not under Wayland. And I didn't know about EWMH, but https://en.wikipedia.org/wiki/Extended_Window_Manager_Hints https://en.wikipedia.org/wiki/Extended_Window_Manager_Hints reads: "Extended Window Manager Hints, a.k.a. NetWM or Net WM,[1] is an X Window System standard for window managers. It defines various interactions between window managers, utilities, and applications, all part of an entire desktop environment. It builds on the functionality of the Inter-Client Communication Conventions Manual (ICCCM)." , well we come to the same conclusion: it's Xorg-only and won't fly under Wayland. Or am I missing something?
