1126991 - CSS animation causes images to only load partially

Status: RESOLVED DUPLICATE of bug 1098958

(Firefox :: Untriaged, defect)

Description

[Gargaj]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0
Build ID: 20150122214805

Steps to reproduce:

The issue is reproducible by visiting
https://dl.dropboxusercontent.com/u/3417034/firefox-css-animation-bug/onlinetest.html
https://dl.dropboxusercontent.com/u/3417034/firefox-css-animation-bug/onlinetest2.html

The page contains two or more images, both animated (translation and rotation) via CSS3 animations.


Actual results:

http://pasteboard.co/HAsUdvf.png - the images (inconsistently) fail to load fully. In some cases, a low-resolution pixelated version is visible instead of the finer version.


Expected results:

The images should've loaded fully: http://pasteboard.co/HAFYOew.png

- The issue doesn't happen if the page is loaded locally, only through network.
- The issue doesn't happen if the image is converted to lower resolution or to JPG.
- The issue immediately disappears if the CSS animation is disabled, even if it's done via Firebug.
- The images themselves are fully visible when viewed through View Image.

The issue happens on:
- FF 34.0, 35.0 and 35.0.1
- XP, Win7, Win8.1, OSX
- Both hardware acceleration enabled or disabled
- NVIDIA, AMD and Intel GPUs

Additional observation: the issue rarely occurs when the page is FIRST loaded, however it almost always happens on a reload.
