  Same as the title.I added the 20-intel.conf with TearFree enable to
  /usr/share/X11/xorg.conf.d.It use to work fine in 15.04.Recently I
  upgraded the system,it was a fresh install,then it happened,really

  Steps to reproduce:

  #Set the Blank after to 1(or whatever except Never) minutes in Xfce Power Manager
  1.Wait until the monitor blanked then wake it.Open a window and shake it,the window is tearing.
  2.Logout and login,TearFree works again.
  Do it again,it's a loop!
