Scrollrect vs. Mask: Smooth movement

[justkevin]

There are two basic ways of panning a view in Flash. One is to move the display object (and use a mask if necessary). The other is to use scrollrect.

Today I noticed a small, but annoying effect of scrollrect. Scrollrect's can't have true Numeric positions-- they are automatically snapped to the nearest pixel.

When moving at very slow speeds, the effect is noticeable. In this example you can switch between two modes of panning, sprite movement with mask and scrollrect:

http://lab.wx3.com/scrolltest/ (view source enabled).

In the default mode, the circles move smoothly.

In scrollrect mode, the circles seem to stutter because the scrollrect is snapping to the nearest pixel.

Has anyone else encountered this and found a way to make a scrollrect move smoothly at slow speeds?

Just right-click on the movieclip. "View source" should be in the menu.
