Confirming problem exactly as described in original description. Freezes are frequently triggered by video playback in browsers, but also in normal browser use. Chrome and other browsers using the Blink rendering engine (like Opera) trigger freezes much more often than firefox. But regularly I can trigger a freeze even in Firefox by showing a video on youtube in fullscreen mode for in than 15 minutes. We provide Ubuntu for 700+ users at a school and cannot switch from 14.04 to 16.04 while this problem persists. It was already present in the last updates to 14.04 we made around march 2016, if this helps. Appreciating your effort on solving this bug!
