Created attachment 141069 [details] kwin wayland backtrace For the past week or so I've been unable to start a Wayland session on my KDE Neon Unstable installation, which is kept up to date. X11 works OK but Wayland just returns me to SDDM. journalctl shows kwin_wayland segfaulting 12 times when I try to log in with a Wayland session. I attach a backtrace. Please let me know if I can provide more info. This is 100% repeatable Also, if I boot the same machine into KDE Neon User edition, Wayland works OK.
