Currently, the there are two frames that happen on property changed that cause the blink. On the first frame, the labels are cleared and the cells are drawn. On the next frame, the labels measure/arrange phase catch up with the cells image drawing and the control is rendered again. Because of this when a cell value is changing at a fast rate (in a timer or similar) and redrawing of the cells is required, a blinking of all texts in the control can be observed.
