Paint Flashing Tool - Firefox Developer Tools
the browser also splits its model of the page into layers that it expects will be updated independently of each other.
... layers are painted independently and then composited, so a change in the appearance of one layer does not trigger a repaint in any other layers, and when only the relation of two layers changes (in an animation, for example) no repaints are required at all.
...so when the element is moved, all that's changed is the relation of the two layers to each other, which is handled in composition: neither layer needs a repaint.
