displaced brush & pencil strokes & never-ending paint brush strokes

above gif shows issues i am having with all 3 drawing tools in aacc19.2:
displaced brush strokes, which may appear slight but are very hindering when animating characters. also shows that the paint brush is creating endless strokes once tablet pen has lifted from screen.
Operating on a Cintiq Companion
Currently AnCC 19.2
19.1, 19.0, and have all shared the same issue.
Windows 10 Pro, 64-bit, OS 17763.437
