I end up with terrible tearing. Usually top of the screen.
Changing deinterlace settings change tearing but it is always present.

HDMI out to amp and then TV.

Here is a fix for tearing

Code:
sudo nano /usr/share/X11/xorg.conf.d/20-intel.conf


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

No, No and no again. This will introduce Triple Buffering and we absolutely don't want that! Cause we are using swapBuffers to update the images on screen. Use the /etc/init/xbmc.conf I provide and you won't have a single bit of tearing. It's all a backing store issue.

As you are not running this howto anyways, fix your lightdm.conf

Fritsch,

If you don't mind, can you explain the negative side effects of Triple Buffering and swap buffer to those of us less familiar with the video rendering pipeline?

I did this as it is listed in the Chromebox entry in the Kodi Wiki as the solution if you have tearing issues. I never had tearing in Kodi, but when I launch Netflix using the NetfliXBMC plugin, I did see tearing. This entry fixed that tearing, but after reading this I am wondering if I may have messed something else up by enabling it, and if I should switch back...

Any additional information you can provide would be much appreciated!
