@wonderbraah@kitecompositor Sorry about that! This may be fallout from Ventura changes to NSColorWell supporting a native popover style.
A (bad) workaround in the meantime would be to relaunch the app and use the gradient color controls before clicking on a normal color well (which steals the color panel).
@tayroga@kitecompositor Yes, still maintaining the app! Making sure it works on the latest macOS. Other commitments are keeping me busy at the moment. :)
