Not that I knew about that feature, nor do I know what it is supposed to do...
It seems that if you scroll through a document, using the "scrollbar"
either by holding down the (left) mouse button
or by clicking & holding within the scrollbar
or by using the mousewheel
the screen does not "draw"
until scrolling is "stopped".
Not exactly stopped, but it is less likely to draw during those times.
And compare that do doing the same when focus is within the document.
Some video players do similar when scrolling through a video clip, where you don't see any of the intervening frames during that period of time.
(Much more apparent on a LONG document/
This might work,

In Everything, dragging the scrollbar, & much like hitting Home or End, is the closest you'll come to that effect.
(I'd much rather have a FAYT, Find As You Type-like, feature in Everything.)
