Since clean installing Ubuntu 15.10, Ubuntu occasionally freezes when I press ESC while watching full-screen videos and has frozen once when I was editing a video in Openshot recently. During most of these freezes, my entire session becomes unresponsive except for the mouse; the only way I can reclaim my session is to either reboot or switch to a virtual terminal and enter kill -9 -1. Other times, all but the mouse and Unity launcher becomes unresponsive, and I could unfreeze everything else simply by launching a program.
Does anyone know why this could be happening? Is there anybody else experiencing the same issues?

Unity was crashing for me when switching from full screen Kodi. I didn't have the flashplugin installed. Instead I fixed the issue by installing and running CompizConfig Settings Manager and disabling Effects->Fading Windows.
