909257 - Animated gif playback not optimal in ux nightly

Status: RESOLVED DUPLICATE of bug 924366

(Core :: Graphics: ImageLib, defect)

Description

[alexander polzin]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release)
Build ID: 20130825040204

Steps to reproduce:

Load any reasonably large animated gif that the browser can't load fully right away


Actual results:

Playback started instantly and proceeded to play back until it ran out of data. Then playback started again at the beginning resulting in loops that kept growing longer the more data the browser received


Expected results:

Playback should start immediately and then stop when the browser runs out of data and not jump to the beginning and start playing again

Provide or attach such a GIF, please.

Comment 2

this for example jumps all over the place during initial load/playback through an admittedly pretty slow internet connection:

Works fine for me on the latest UX Nightly build (compared by playing the gifs from Comments 2 and 4 on Chrome 30.0.1599.69)

Alexander, are you still experiencing this issue? Could you please verify whether the issue is still reproducible if using Firefox with a new profile?
