My understanding of rubberband is a rubber square that marks the cell, when multi-selection cell's/row's mode is enabled. Maybe you mean a focus-frame around the cell? Can you attach a screenshot showing the problem?
I've attached a screenshot with a single cell selected showing what I think is the rubberband around the cell (dotted white border around inside edge of the cell). Maybe my idea of what the rubberband is incorrect.
Also, what does setShowFocusDecoration(bool) control?
