1154089 - Hover on images in containers (possibly anchors) that are not the size of the original image causes images to jump around and appear in the wrong place

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[Neil Kessler]

Attachment: screenshot.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20150402191859

Steps to reproduce:

Hover over images in anchors where the original image size was not the size of the container it was inside of.  


Actual results:

The image that is supposed to be in one anchor appears in the wrong place, sometimes flickering in and out, sometimes staying if the mouse stops moving.  Several images will move as well, sometimes not even the one that I am hovering over.  I've attached a screenshot for another site I also found it occurring on.  The bottom row should have four separate images and you can see that two of them are appearing in more than one place when I hover on the one to the bottom left.  The url is: http://www.foundersfund.com/our_team/


Expected results:

The images should not be appearing in the wrong place.  Looking at firebug shows that there's no actual code change, but on the screen they appear in the wrong place.

- I also get the same bug, although only on some devices. 
- The error also doesn't occur when hardware acceleration (in Settings-> Advanced -> Browsing) is turned off.
- The error started to appear in Firefox 37, I tried a portable version of Firefox 36 which didn't have the error.
- It also appears without any plugins.
