Hi,
I've just merged a patch that tweaks some protocol additions in the
plasma window management protocol that were made this month and haven't
been released yet.
Even though that change won't affect users running stable version of
plasma, it may cause issues on developer machines.
If you experience startup issues with plasma on wayland, in particular
plasma not starting at all, please recompile the following projects:
* plasma-wayland-protocols
* kwayland
* kwayland-server
* kwin
* plasma-workspace
Sorry for the inconvenience,
Vlad
