This works fine when the new y value is a whole integer, but I'm
seeing some strange behaviour when trying to scroll by fractional

Are you sure you want to scroll by fractional pixels? It will be
slower, because the view has to re-render from scratch, instead of
letting the video card scroll the pixels.
Is one set to copy on scroll and the other not?
But yes, it's a bad idea, IMO.
