I was able to resolve my issues but only after things got worse; I 
started seeing X server (Xorg) crashes:

     (EE)
     (EE) Backtrace:

I tried downgrading nvida-driver from 460.80 to 460.73.01 but was still 
seeing crashes so I tried swapping my Quadro 410 with another desktop 
and the kicad/chrome issues followed the card; the card has clearly 
failed and is headed for a nearby e-waste bucket. I'm now back with 
460.80 and while the lastest firefox (89.0_2,2) is still sluggish at 
times the screen artifacts and X server crashes seem to be gone.
