I can reproduced the gnome-control-center crash on Lunar. The crash only happened when two monitor can't find match resolution. My laptop's internal display only has one resolution 1920x1200, external monitor's highest resolution is 1920x1080. When switching to mirror mode in gnome-control-center, it will crashed.
