After opening all sections in 'Digital Clock' widget settings applet - there are next entries with 'Binding loop' text in '~/.xsession-errors' file:

cat ~/.xsession-errors | grep 'Binding loop'

file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/ScrollView.qml:227:9: QML Binding: Binding loop detected for property "value"
