Lower layers appear to be expecting only a difference since the last RISC OS position update though, not a distance-from-centre, so things get out of hand quickly.

Perhaps it requires a Qt build which *does not* properly support move-mouse-cursor, so move-to-centre is ignored and the differential position logic calculates correct positions by accident?

I had a play around with the source, and I don't think that mouse positioning works on macOS. I've not tried any other platforms.

I seem to be missing the patch attachment. Does it show up for anyone else?
