I booted the latest (from github) Manjaro KDE on a Pi-5. It booted quite quickly. However, i was immediately greeted with a flickering mouse cursor. The cursor even vanishes unless i move the mouse. That was an issue with KDE-5 wayland on Pi-5 also. I do not remember having this issue on Pi-4. And also, it goes away if i switch to X11. I would think that the latest KDE Plasma (6) would have solved these issues but i guess i was wrong.
