Ever since I upgraded to Ubuntu 15.10, I haven't been able to exit fullscreen without video crashing. There are rare cases when I've been able to safely exit, but more times than not, it doesn't. This is typically when I'm using Chrome to watch YouTube or Twitch video streams. The only way out is switch over and do a "killall -u myname".

To quote myself elsewhere:
"I upgraded to 15.10 almost immediately after it was released, and have been suffering from this issue ever since (15.04 worked way better than 14.04, so I had high hopes). It mainly crops up for me in Chrome, and ruins my day when I accidentally press YouTube's fullscreen shortcut key. The only way out has been to "killall -u myname". I had hoped to find this problem resolved, but with Ubuntu 16.04 looming, it's kinda crazy that it isn't.
It's worth noting it isn't a typical crash. Video becomes mostly unresponsive, with the exception of the mouse cursor that can still be moved (has no effect though). Audio continues to work, even YouTube and Twitch that are streaming, there is just no longer any useful display. Other reports seem to suggest disabling hardware acceleration in Chrome works around the issue, but that's not really acceptable because of the need for WebGL and such."
