I am using Arch linux with i3wm on my Lenovo x390 yoga notebook. I am experiencing weird glitch during fast changes on screen (videos, games, cursor movement).

The glitch are horizontal lines dividing two slightly shifted images. It is caused by refreshing only part of a screen. There is an image of same issue:

vsync glitch

I do not experience that big distortion like on image but it is very noticeable and annoying. It is not dependent on any program. I experience it everywhere.

How can I diagnose and fix this issue ?

Session type:

john@arch-thinkpad ~> echo $XDG_SESSION_TYPE
tty

PS: If you need more information just tell me in comments and I will quickly provide it to you.

It was solved by creating /etc/X11/xorg.conf.d/20-intel.conf file with this content:

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"

  Option "TearFree" "true"
EndSection

and rebooting.
