I've been using Libreelec (and kodi) for ages on my Pi3, works fine - but underpowered for 10bit content. I've gotten a Minix U-9H box, running Libreelec too (community build).
I noticed quite a bit of video stuttering (audio remains fluent) on the Minix box, and after investigating, it seems that doing refresh rate switching fixes this.
Strangely enough, I didn't have refresh rate switching switched on on my Pi3, and here I don't have any stuttering.
I know they're two completely different platforms, but any ideas how this might be? I've checked all other parameters, they're identically configured on both instances of Kodi (17.6).
Problem is that doing a resolution switch is slow (on my TV it takes a few).
