flatpak info (-M) $app

I attached the output of:
```
for app in com.skype.Client com.valvesoftware.Steam io.atom.Atom
org.signal.Signal org.zulip.Zulip
  flatpak info $app
  echo Permissions:
  flatpak info -M $app
end
```

What sticks out is that the applications crashing all have `devices=all` or
`devices=dri` permissions -- i.e. they can access the GPU directly.

Running /var/lib/flatpak/app/io.atom.Atom/current/active/files/bin/atom-real
directly, without Flatpak, locks up the entire system hard -- ctrl+alt+f2,
ctrl+alt+del, SysReq+REISUB all do not help and I have to hard reset the
machine.  No logs are available from this run.
