Firefox HTML5 replay with artifacts

Strange thing is happening for quite some time now with my Firefox when playing HTML5 videos. First play of video is flawless, but when I click on replay on Youtube or Firefox automatically replays HTML5 wrapped GIFs, image starts to tear and display artifacts. It looks like when you jump in video, but player was not able to load and display all pixels of image, but this is not the case because previous play of video was correct. Only solution is to reload page.

This seems to be only Firefox HTML5-related issue, as HTML5 in Chromium or Flash videos in Firefox plays flawlessly. Also every other video in system. Because of this I don't think this is hardware/driver/compositor related issue.

I'm using Debian 8 Jessie with KDE and current Iceweasel 38.0.1 (rebranded Firefox, but this shouln't matter). My VGA is Intel Sandy Bridge.

Attaching example of artifacts in GIF image. Before and after replay.

This is going to be due to a change in quality of video picture provided by the media service that you are using to display the media.

In other words it will depend on the internet quality. However if this does not happen in other browsers you can consider this:

I don't see how this could be connection issue, because first play of video/gif is flawless and after that video is loaded in memory (besides my connection is 50/10 Mb/s, so caching is really not a problem).

I should mention that I've tried all the basic fixes - running in safe mode, running without HW acceleration, clearing cache.
