  Hmm, I understood this differently. I thought this happens when you react to each input event sent by the kernel, regardless of its delta, like e.g. the old gwenview code did which you linked: it just zooms in once per event. Thus devices which generate more events with smaller deltas zoom in faster, which is not good. And this bug is definitely at the application level, not in libinput.
