Public bug reported: If I dare to launch any electron-based app (chrome, spotify, atom, vscode, etc.) there's roughly an 80% chance that it kills X (bringing me back to the login screen). This doesn't _always_ happen. Note that I have a 4k laptop, with a 4k external screen. Things seem to have a better chance of succeeding if I disconnect the external display before launching the electron app. Once it launches successfully things seem to be stable, even after re-connecting the external display.
I SSHd into this machine from another, and connected to X from gdb, then opened vscode to cause the crash. Here is the backtrace I got from that session (this is easy to reproduce, happy to provide any requested info): root@Pandora:~# gdb /usr/bin/Xorg $(pidof Xorg) GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.5) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.
