Nvidia

Installed with 

local/nvidia 570.124.04-3
    NVIDIA kernel modules
local/nvidia-utils 570.124.04-1
    NVIDIA drivers utilities

originally installed 

nvidia-open

BOTH  caused weird artifacting/flickering in the bottom right of the screen

FLickering may be caused by a weird scaling.

I set scaling to 1 and now it seems to be working fine opposed to the original 1.5
