I put the embedded version of 1.8 on an MSI Cubi (Intel Core i3, 8GB DDR3L, 64GB M2 SSD) and it is very flaky. There is a lot of screen flicker on interface items. Sometimes sections of menus black out in blocks. Sometimes multiple items light up and stay lit when navigating menus. In short, it is borderline unusable. I'm going to go back to 1.6 for now.
Ran into that issue lately with my set-up. Was moving some hardware around and put 1.8 embedded on some AMD hardware and had the interface flickering/shearing issue. Tried the 1.7 install and it seemed be fine. Issue after that was I couldn't get the audio pass-through to work correctly to my receiver. Switched back to some Intel hardware and ran fine on v1.8 and audio pass-through worked fine.
Was hoping to use the more powerful Intel hardware for a pfsense router install (it's a bit overkill for an openPHT client) but just couldn't get the AMD hardware to work 100% on 1.8
