      Could it have something to do with the current index being modified when you change the model data? Something in the vein of:

        @Diracsbracket this did not work for me I am doing the same operations but strangely going in different directions

        ListView {
        ...
                onContentYChanged: {
                    if(contentY > 0) {
                        savedY = contentY
                        console.log(savedY)
                    }
                }
        
                onModelChanged: {
                    contentY = savedY
                }
        }
        

        Result (Video)

            Hello,

            Did you check if you are getting a binding loop when the slip occurs?
