VC-1 1080p24 Visual Artifacts in Kodi on Lubuntu 15.10 with VAAPI acceleration

Gentlemen, not sure if this should be in this thread, so if not, mods, please move it to the appropriate thread.

I am having issues with some 1080p24 VC-1 files having visual artifacts when VAAPI hardware acceleration is enabled. The artifacts do disappear if I turn hardware acceleration off, but then the video stutters (not enough CPU power).

I am running Kodi media center on Lubuntu 15.10, 64 bit, Kernel 4.3.3. The system is:

ASRock N3000 with Crucial 2x4GB RAM kit and a 250GB Samsung 850 EVO mSATA drive. My UEFI version is N3000-NUC P1.50, CPU set to Sport Mode. 

I cut a section of the video I'm having problems with, and a member on the OpenELEC forum confirmed that they have the same problem on ASRock N3000. I uploaded the section of the video below.

I tried updating the driver using Intel Graphics Installer for Linux (1.2.1), but nothing changed. Tried using Intel Graphics Stack Release 2015 Q4 (to update to version 1.6.2) but couldn't figure out how to compile and install it, as the very first thing I'm trying to build is libdrm and the line ./autogen.sh --prefix=$MY_DISTRO_PREFIX gives me error, as there's no autogen.sh. I used configure, but also unsuccessful.

 

I had the same issue with OpenELEC. I tried to address this issue on the OpenELEC and Kodi forums, but was refered to get more support here. OpenELEC forum thread is here: http://openelec.tv/forum/116-vaapi-intel/79224-asrock-beebox-n3000-vc-1-...

 

Here's the output of $ cat /proc/cpuinfo | grep -i intel:

Any help on how to update to i965 driver version 1.6.2 to try it or other help is greatly appreciated. 

 

Thank you.
