925550 - [B2G][Email] Scrolling marquee for long email addresses in the action menu header glitches when address reaches 34 characters before the @ symbol

Status: RESOLVED DUPLICATE of bug 929362

(Core :: Graphics, defect)

Description

[Matthew Vaughan]

Attachment: Video of tapping the screen to make the long email scroll in the header.

Description:
The automatically scrolling marquee for long email addresses in the action menu header appears to glitch when the email address reaches 34+ characters before the "@" symbol. In order to make the marquee visibly scroll, the user has to tap the screen repeatedly.

Repro Steps:
1) Update Buri to Build ID: 20131010004001
2) Launch the Email app
3) Tap on the Create New Email icon (pencil in a box)
4) Tap on the "To:" text field
5) Type a fake email address containing 34+ characters before the "@" symbol
6) Tap on the contact bubble

Actual:
User must tap the screen repeatedly in order to have the email address scroll in the header; marquee scrolling glitches.

Expected:
Email address automatically scrolls back and forth.

Two questions here:

1. QA - Can you check to see if this UX is horizontal scrollable?

2. UX - Was there any intentional UX change here to move away from marquee? If not, what's UX take on the severity of this bug?

We're still using the exact same marquee logic as we have been since this feature was implemented.  It's a non-interactive (no scrolling by the user) CSS keyframe animation on translateX that takes 15 seconds.  See marquee.js and marquee.css in the e-mail app.

I suggest looking for other bugs in the same time-frame related to platform graphics regressions and duping this to that.  From the video and description it appears that the animation keeps running in the background, but only repaints when the user taps the screen.  There might be something interesting in the logcat for graphics engineers.

Okay. On that basis, bouncing over to gfx.

Actually works for me on Unagi, but I do have some local changes.  Do we have a reproduced case on other devices?

It reproduces on Buri. If I recall, there's some differences in what preferences are enabled on Buri vs. Unagi, right? It probably has something to do with that.

If you want, we could check this on a leo device as well. Let me know if you want that.

Markus, looking for somebody that can triage this in CSS animation/graphics - can you take a look?

I've verified that the patch in bug 929362 fixes this. Yay!
