After the Plasma 6.7.0 update on Tumbleweed, System Settings crashes when I click on Colors & Themes> Login Screen (SDDM). I’m running an Intel ARC A750 and Wayland. I need to know if this is a Plasma 6.7.0 bug or a Tumbleweed bug.
Running systemsettings kcm_sddm in a terminal starts System Settings at the Login Screen (SDDM) configuration page and I am able to navigate to other settings and return to the SDDM settings without issues. It also prints warnings about themes in the terminal, but no errors.
When I run just systemsettings in a terminal, it crashes like it does from an app launcher, except I get some warnings about themes and an error about X.
