Public bug reported:
I have a DisplayPort switching arrangement consisting of a 4way DP
switch that switches 2, daisy-chained DP monitors.
Many times, but not always, when switching the displays away from this
host, gnome-shell crashes. Later, switching back, I'm presented with the
gdm login screen, previous session is gone.
