dhh proposed and merged omacom/omarchy#16923 into Quattro, replacing persistence through a shared scale setting with a rule for the focused monitor. Changing a laptop panel's scale should therefore stop changing an external display after configuration reloads.
In follow-up responses, dhh described atomic writes that preserve configuration symlinks and safeguards that leave complex monitor rules untouched. dhh then merged omacom/omarchy#16950 to derive session-wide GDK_SCALE from the lowest enabled monitor scale. This addresses oversized XWayland applications on a lower-density screen, with the stated tradeoff that they can appear slightly small on the denser display.
