GUI Lag on Mac Sierra using Audiobro Genesis

Anyone else who owns Audiobro’s Genesis experience lots of GUI lag when riding the mod wheel? This isn’t a show-stopper for me (it doesn’t affect the audio), but it seems concerning. I’m curious to know if this will become something bigger in Cubase 10 or if this is locally produced issue.

The links below have Genesis in Kontakt 5.8.1 using Cubase 10 and Cubase 9.5. There’s a major difference between 9.5 and 10 (it’s also very smooth in Logic Pro). I’m running a 2013 Mac Pro with the D500 GFX card NOT using a 4K monitor – just a standard Dell LCD – so I’m pretty sure my GFX card is plenty powerful enough.
