>>>This has plagued me for a while. Anything dockable, when moved, throws up this shadow, offset up and to the left, making it nearly impossible to properly align things.

If you can work with a lower resolution that could make it better. So instead of changing the display scaling you set a lower resolution, although the effect is not as good, especially on notebooks, it at least helps a little.
