It even does it when I don't have it in full screen

you need to have FSE enabled but also turn on full screen windowed mode in KODI itself, turn it off in MADVR.

Have you got your modes set correctly in MADVR:

2160p23, 2160p24, 2160p25, 2160p30, 2160p50, 2160p60

Also what are your rendering times, they should be sub 30ms for smoother playback, ideally sub 20ms 

modes are set correctly. rendering times bounce, generally from about 25 to 28ms. I downloaded the hotfix driver, but haven't tested it just yet. It was all over the place yesterday. Would work for a minute, then start jittering all the way to just jittering as soon as I load it. Will report back later with the new hotfix driver test. There isn't really a whole lot to look for with this card either. Other people have reported problems, ie hotfix driver, but nothing to do with this though.
