After upgrading to Plasma 5.23.3, Plasma X11 session is locked to apparently 200% scale. It has nothing to do with screen's physical PPI, it will set scale to 200% by default on anything screen. I can change the scale to 100%, but it has no effect. The scale is locked on 200%. It's applying this scale on the SDDM login screen as well. Plasma Wayland session is not affected. Operating System: Arch Linux KDE Plasma Version: 5.23.3 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2
