Are you playing a movie from the sd card or network when you get these artifacts? Are you on the latest JetPack?
Using the latest docker image I can stream an 80Mbit H265 file with no problems when hard wired on Ethernet on a Jetson Nano 4GB.
 

The movies are either on a directly connected USB-HDD or on a LAN-connected NAS. Both show the same issues.
My Nano is running Ubuntu 20.04.3 LTS (GNU/Linux 4.9.201-tegra aarch64) from USB, JetPack 4.5.1 (LAT 32.5.1) is installed.

I am running 2 different Kodi-installations alternatively:
   1) currently for testing: the one provided by  https://github.com/aliubimov/xbmc.git   and 
   2) for daily use: a installation w/o using the GPU. Here I see no issues with H264 movies, but some stuttering with H265 movies together with 100% CPU-load
Based on this, I assume my problems are not caused by data-access.

Maybe I'll find some time to update my Nano to the most recent JetPack

Thanks!
