Capture One v11 doesn't like Huion tablets/displays?

I'm having problems using my Huion display tablet with C1 v11. When I draw a mask nothing appears on the screen until I stop and lift the pen off the screen. C1 also does not recognize the pen pressure either. I will either get pixel-thin squiggles or maximum brush width smears. Everything was fine with C1 v10.

All my other applications work just fine with the display tablet and have no problems sensing the pen pressure.

Has anyone experienced this on their Mac?

Thanks!
