User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20130401 Firefox/21.0 Build ID: 20130401042013 Steps to reproduce: I have two thumbnails on this page: http://company-mode.github.com/ These are .png images, resizing is done via scaling on the fly. I have the "width" attribute set on the images, and setting or leaving out the "height" doesn't change the behavior. When the webpage is updated, to get the current problematic version, do: git clone firstname.lastname@example.org:company-mode/company-mode.github.com.git git co 39711bfd12ed3e8d7f67d3b52f20b7d5f4f92748 and open index.html locally. Actual results: After the page loads, both images flicker as though switching to a different scaling algorithm and back. Same thing happens when I switch to another tab and then return. Expected results: The images shouldn't flicker. In IE10 and Chrome Canary 28, they don't.
If you change the preference image.high_quality_downscaling.enabled to false, does the problem go away?
Yes, it does. And if I change it back to true and switch back to the opened tab, the images flicker again.
