Minix X8-H Stuttering on YouTube & Twitch

Hi All,

I have 2 Minix Neo X8's and both of these boxes suffer from stuttering video on YouTube & Twitch. Could one of you experts tell me where I'm going wrong as YouTube works on my most basic android phone. All other videos work fine on MX player for example. Is there going to be an update to fix this or has there already been that I might have missed. Please Help as anything I watch on these 2 websites is basically unwatchable.

Thanks in advance
