942259 - Folder list scrolling seems broken

Status: RESOLVED FIXED

(Firefox OS Graveyard :: General, defect)

Description

[Lucas Adamski [:ladamski]]

Trying as hard as I can, I can only get the folder list to scroll by 1-2 pixels at a time.

Peak 1.2 build, latest nightly.

Comment 2

[James Burke [:jrburke]]

This seems global with last night's nightly: I noticed it in the Settings app too.

Maybe something got uplifted to v1.2 recently?  We were seeing something like this on master in Brussels/summit on a nexus 4 I think and my general hope had been that there was just a regression someone would fix.  Brief discussion in #gaia was that we probably have iframes that are eating most of the scroll event, leaving us with only a few pixels of scroll.  (It sounded like this was buggy distribution of the scroll events, though, since we really only have one iframe that should be doing stuff.)  My most recent hope would be that our drawer overhaul for v1.3 would just fix/workaround this.  But if it's somehow gotten to v1.2, that's very bad.

Tragedy of the commons. :)  Please file all bugs you see, esp. on master so we can catch these before they uplift.

Lucas, 

Could you please provide STR and environmental variables (gecko,gaia,build ID and device)? If we can get those, we can find a regression window. 

Thanks!

To expand on comment 1, peak 1.2 build id 20131121205355 (geeksphone daily builds), git 2013-11-21.  Sounds like it dates back to at least early Oct on central per comment 3.

STR:
open email app, try to scroll folder list.

That may be a regression from Bug 914854 that landed Oct 1. I can't repro on my helix, I'll check on a 320x480 device asap.

Attachment: panning.patch

That fixes the issue for me.
