I've been trying Wayland for quite some time, but Wayland is a chore to work with and most applications still needs to use the xwayland compatibility solution anyway. After a long time of using it I decided to just switch to X11 and save myself the stress. However after seeing this and reading some comments I decided to try it out yesterday (maybe stuff has changed?) and then turned off my PC and went to bed, then today kwin_wayland started crashing for no reason. For a supposedly superior display server, it sure has a lot of issues and low adoption.
Maybe the Wayland developers should consider it a failed project and work on X11 instead?
