Crippling your system (switching to xrender and much slower nouveau driver) is not a solution. What works for me flawlessly for more than a week on KDE Neon: In file: /lib/systemd/system/sddm.service Add: ExecStartPre=/bin/sleep 10 After [Service] The problem apparently is that something SDDM needs is not initialized before is starts, so delaying SDDM by 10 sec is adequate workaround. Perhaps it could be less, but it doesn't bother me as long as I don't have to log out/log in manually.
