Bug Description

According to: http://library.gnome.org/misc/release-notes/3.4/#rnusers.smooth-scrolling,

we should now have smooth scrolling in GNOME 3.4, if I'm not mistaken. But to me, it seems all scrolling is still quite "jerky" (or "normal/classic", if you will).

Do they mean, in the release notes, that smooth scrolling is "available" in the sense that applications have to embrace the possibility in their code, or should it come automatically to all applications? I'm not seeing any smooth scrolling as of yet.

The overlay scrollbars thing does exhibit smooth scrolling, even since 11.10, but I turned those off because I hate them. But with overlay scrollbars off, I don't see smooth scrolling in GNOME 3.4. What do they mean in the release notes?

This bug report isn't related to Gnome Shell, and I'm pretty doubtful that it should have been converted from a question :/

Try the following:
- Use supported hardware with a driver that supports new-fangled scrolling stuff. For example, a Synaptics touchpad
- Use an approach to scrolling that logically provides pixel-perfect information, such as two-finger scroll.
- Try scrolling a list view in a Gtk3 application.

Not all applications do smooth scrolling yet, because it requires some API changes. If you try Nautilus, Gedit or Rhythmbox, smooth scrolling should work throughout. If you find that smooth scrolling definitely does not work in those applications, and you know your hardware should be supported, please do let us know.

So, correct me if I'm wrong here: Basically, smooth scrolling is not available for regular mice. It's more for touch pads. Is that kind of the gist? Because I don't think I have access to any of those things to try.

That's the gist of it, sorry to say. I think hardware support might improve in the future, but it's important to note the feature in the release notes is perhaps better described as 1:1 scrolling (with some kinetics). It is not the other kind of smooth scrolling, which is animating between scroll stops (seen in Firefox, for example).

Oh I see. Okay, thank you for that information, Dylan. At least I know now that I'm not missing out on a feature I'm supposed to have. Thanks again!
