I've noticed login out of Wayland ends up with a number of KDE apps crashing, 
rather than exiting gracefully.  I think kwin is one of them, as well as 
KDEPIM related apps, perhaps others too.

Wayland is much more stable today than a year ago, but I think as far as 
Plasma is concerned it's not yet ready for production time.
