Grabbing hand cursor is not recognizable
yaru-theme-* 18.10.4, Ubuntu Cosmic
The grabbing cursor is extremely abstract: there are no visible fingers, no visible knuckles, and the thumbtip is square.

In earlier versions of Ubuntu, the cursor was much more recognizable as a hand: four visible fingers, three visible bottom knuckles, and the thumbtip is bent inward.

Neither of these are ideal: they show the kind of grip you’d make around a handlebar, which is very different from the kind of grip you’d make on a flat object on a flat surface, like a sheet of paper or a calculator resting on a real-life desktop. For that, the fingers should appear spread out.
Making the grabbing-hand cursor more recognizable might involve changing the pointing-hand cursor to match.
This issue is not about any particular app using the wrong cursor in a particular situation.
