in accordance with identifying that the first execution window and the third execution window overlap at least in part, determining a second non-overlapping region not obscured by the second execution window and the third execution window in the rendering region of the first execution window;

identifying a third rendering frequency for displaying the visual object in the second non-overlapping region based on the determined second non-overlapping region and the rendering region; and

displaying, via the display, the visual object in the second non-overlapping region at the third rendering frequency.
