Still crashing on Neon unstable edition.
open system settings in icon view mode
open display and monitor
change scale setting or select a unselected radio button on bottom
click on "All settings" in the upper left corner (system settings prompts
to save/discard change)
click on "Discard" button
system settings crashes
