Xfce Screentearing

Tested myself on Xfce 4.12 on Xubuntu 20.04 on trenzalore (Intel HD Graphics 530), allegedly works on Xubuntu 16.04.03.

Create file /etc/X11/xorg.conf with the content:

        Section "Device"
            Identifier  "Intel Graphics"
            Driver      "intel"
            Option      "AccelMethod"   "sna"
            Option      "TearFree"  "true"
        EndSection
