I have a similar bug, but i'm not sure if it's the same issue. I'm not using compiz as far as i know and i don't think i have the workspaces enabled. But after upgrading from 14.04 to 16.04 my system freezes often when chrome is up and a video. It almost seems like a memory problem, but perhaps it's related to the graphics driver. Here is my bug that i reported. If it's not the same, then just ignore my comments. But it's a serious problem.
