I really want to use wayland - and even though maybe I shouldn't I still do on my laptop - but man... on Plasma 5 that thing is borked. And I'm not even running on NVIDIA.
Whenever the system wakes up from sleep or an external display reconnects all open windows are gone and the system enters a weird state which forces me to reboot. How was "all windows are lost when the compositor crashes" not something fixed in the early days, is beyond me. That must make even developing for Wayland unnecessarily difficult/annoying.
