I'm using DMA2D to draw images on the display. I'm using two layers and both of them will eventually be animated. But at this time I'm trying to move just one object on one layer around the screen, but the entire display flickers each time the object is redrawn. What are the sources of flicker on displays, on what could I potentially be doing wrong?
