Hi, i have the same issue with Khadas VIM2 MAX (3GB/64GB). I installed VIM2_DualOS_Nougat_Ubuntu-16.04_V170818. On Android video playing smooth (Youtube, IPTV from my local IPT multicast over IPTV app, etc). In Ubuntu trying Kodi, VLC and can’t playing smooth video. Big lag in Youtube by Chromium, Firefox. I’m disappointed with the device because for me it’s only possible to surf the web through Ubuntu. For whom is the official Ubuntu firmware if almost nothing can be done with it?
