When/if GParted is ported to gtk3, THEN the work around can be removed.

In the mean time the xhost workaround enables people to continue using
GParted.

Title:
  Xwayland not using XAUTHORITY, prevents root applications from
  connecting

Status in gdm:
  Confirmed
Status in GParted:
  Fix Released
Status in Ubuntu GNOME:
  Invalid
Status in gdm3 package in Ubuntu:
  Won't Fix
Status in gparted package in Ubuntu:
  Invalid

Bug description:
  When running wayland, GDM fails to set up an XAUTHORITY file and instead
  relies on the process UID for authentication.  This prevents
  applications run as root, like gparted or synaptic from connecting to
  the server.  GDM needs to set up the XAUTHORITY file when running
  Xwayland just like it does when it runs the conventional Xorg.

  A large list of applications broken by this can be found here:
