Well folks, it’s the beginning of a new era: after nearly three decades of KDE desktop environments running on X11, the future KDE Plasma 6.8 release will be Wayland-exclusive! Support for X11 applications will be fully entrusted to Xwayland, and the Plasma X11 session will no longer be included.


That could be but it’s not universal to all machines running anything NVidia+Plasma+Wayland as you made it sound in your original post. That is the clarification I was trying to make.
Not sure if you tried, but you can also bridge the gap with XWayland
I run the omnissa client (Horizon client from VMWare) on my daily driver on Wayland even though it’s not supported. The client complains every day but works flawlessly
