1151986 - [Music][Slider/Scrubber] The slider and song time will become frozen when trying to tap multiple buttons at once

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Music, defect)

Description

[Derek Harris [:DerekH] - Dont need info. Last day 6/5/15]

Attachment: Music Slider Logcat

Description:
If the user tries to tap the back button, or the play/pause button while they are pressing on the slider, all of the UI in the music app will freeze, but the music will contine to play, and buttons will still function. It should be noted that I have gotten this by sliding the slider around and having my finger slide over the star rating, or play/pause button. The "tap the back button ~6 times" step is just the easiest way to reproduce.


Repro Steps:
1) Update a Flame to 20150407010204
2) Open Music app
3) Select a song
4) Tap and hold the music scrubber
5) While holding the scrubber, tap the back or pause button ~6 times quickly
6) Let go of the scrubber


Actual:
Scrubber and music time will be frozen, but music will contine to play


Expected:
Nothing is frozen. Everything plays as expected

NI on component owner for nomination decision and assignment.  Visual Regression that can be recovered by tapping the play button or the slider.  Also music continues to play.

Comment 3

[No-Jun Park [:njpark]]

The multitouch is technically not supported by the Music app UI, but it's interesting to see the UI freezing, ni?ing Jim in case this points to a more serious underlying issue.

Comment 4

[Jim Porter (:squib)]

I feel like we have a similar bug on file about this, but I can't find it...

Comment 5

[Jim Porter (:squib)]

Oops, hit enter too early.

This is probably due to some weirdness surrounding how touch events work. Probably, the scrubber never gets the touchend event, and things get confused.

Comment 6

[Jim Porter (:squib)]

I don't see this in the NGA version of the app anymore. Could you take a look to see if it's fixed now?

Comment 7

[John Thomas [:Johnt]]

This DOES still repro on Aries 2.5, Flame 2.5 and Flame 2.2
Result: Scrubber and music time will be frozen, but music will continue to play.

I *think* I reproduced this? I dunno. I was able to get to a blank screen by scrubbing the slider and hammering on the back button. Taking this to try and improve robustness of the "back" button.
