Re: APZ enabled on Fennec nightly

Thanks for hard the work on this! I'm happy you're working on improving the 
scrolling.


Since the change, I've noticed a few things:

1. Reader mode's toolbar now sometimes seems to jump up and down several times.

2. Deceleration takes too long to happen (the page seems to just float for far 
too long after flings happen, especially for slower, smaller flings). It's much 
slower than other apps, and it also feels much slower than I remember for 
Firefox before the update.

3. Quick flings don't jump up or down on the page as quickly as they previously 
did, making more work to get back up to the top of a page, or to quickly jump 
down to read the summary paragraph of an article.


This is all on a Nexus 6P running stock Android Marshmallow, by-the-way. It 
might feel different on other devices.


Again, thanks for working on this! I know it's a WIP in Nightly it's probably 
subject to change a little with a few tweaks.

Cheers,
Garrett

Thanks for trying it out and reporting these issues! I've filed them
as separate bugs - bug 1229840, bug 1229839, and bug 1229841. We
should be able to address 2 and 3 by tuning some prefs, 1 will take a
bit more investigation.

Cheers,

Excellent, Kats!!

Perhaps this will also unblock smooth scrolling and scroll snapping for fennec.

Yes, I will be testing those features on Fennec later this week and
enabling them as well if they work well (or investigating why if they
don't). :)

APZ enabled on Fennec nightly

[Kartikaya Gupta]

Hi all,

Just a heads up that I landed the patch to enable APZ on Fennec
(nightly channel only for now). It should be in the Dec 1 nightly and
onwards. This will make scrolling around, and general touch input
handling, feel different on Fennec. The main improvement should be
that scrolling of iframes and overflow:scroll divs will be smoother
and faster.

If you find bugs, or behaviour differences that you feel make things
worse, please file them in the "Graphics, Panning and Zooming"
component of the "Firefox for Android" component and we'll take a
look.

Thanks!
