[Avid-L2] Artist Color Panel very degraded in Resolve 16 OS 10.13.6 vs. Resolve 15 OS 10.12.6?

I've been beating my head trying to test my Artist Color Panel in Resolve 16 OS 10.13.6.  It's just awful and I don't remember it being that way before in my classes etc...  Today I went back to my 10.12.6 startup Resolve 15 and the panel is very smooth like I remembered.  Has anybody noticed the degradation of the sensitivity/perrformance of the Artist Color Panel on Resolve 16.  I'm using the same Eucon software on 10.12.6 and 10.13.6 as that hasn't been updated because the panel is EOL.  I can't install Resolve 16 on OS 10.12.6 so I can't tell if it's Resolve 16 or Eucon/10.13.6 issue.  I wish Resolve would at least let me risk installing Resolve 16 on 10.12.6.  I know this is old hardware but it works fine on the 10.12.6 startup.

I'm going to borrow another Artist Color Panel from a friend to doube check and also hist BM Mini panel.  It really feels like Resolve 16 may have crippled the Artist Color even though it is still an option in the pulldown menu.  Or it's OS 10.13.6/Eucon?  Nothing like herding software cats.

Anybody seeing what I'm seeing?
