To reproduce the problem, open the attached slideshow (index.html), place mouse on the image of iOS, let the image grow for a second or so, move mouse somewhere else. The bug is nearly 100% reproducible with this sample.

Also useful to know if this happens with different accelerated (or not) layer backends.

The comment wasn't directed at you, but anyone who could test. You can uncheck use hardware acceleration in prefs under Advanced, General.

I have tested with HWA enabled/disabled. Is this still reproducible on your end ? If yes, can you please retest this using latest FF release and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E).
