I'm not sure this is a macOS bug, a Chrome bug or something else but my macOS crashes when I'm watching fullscreen video in Chrome. By crashing I mean that I'm suddenly logged out from the system and all apps are closed. This happens very quickly in about a second, like I'm watching a video and suddenly I'm on a screen where you choose an account to log in macOS.
This happened at least 5-6 times since I installed macOS. I've never noticed same behavior on previous OS X versions.
Has anyone experienced the same? Is there any solution?
P.S. I'm testing this in other browsers and will update the question with results.
