SetCursor_()

I set custom cursors for my app window, depending on the whereabouts of cursor in the client area. It works perfectly but if the mouse is moved rapidly, you can see a flicker of the regular cursor on top of the custom cursor. This requires a bit of effort to actually get it to occur on XP and Win7 but is much more noticeable on Win8.

That sounds very much like the underlying cause. How do you set the class cursor to null?If your application must set the cursor while it is in a window, make sure the class cursor for the specified window's class is set to NULL. If the class cursor is not NULL, the system restores the class cursor each time the mouse is moved.
