Redraws when selecting vector features

Why is it that GM sometimes does a full redraw to select AND deselect a vector feature - and sometimes not? At first it seemed to be that this happens when vector features continue off-screen; but that's not universally true either. I use large area DEM's and hi-res imagery with vector features over those and that makes the redraws pretty long. So just editing half a dozen lines can be agonizing when this is happening. Since sometimes there is selection without a redraw, I know it can happen. What's actually going on with this?

Thanks for an explanation so I can perhaps find a way to cut down on dead time.
