I have had a similar problem with flickering when I was using DirectDraw
to display changes in the mouse position. What I did was instead of
updating every time no matter what, save the old value in a variable,
oldValue for example. Every time you get the new value:

if ( newValue != oldValue )
{
	oldValue = newValue;
	... 	// update display
}

If the value changes frequently then you will still have
some flicker, but there will be little or no flicker otherwise.
