Ndisplay render artifacts - banding via movie render queue - bug report

I’m not sure where I can register this as a bug, so I’m posting here for the time being.

Above a certain threshold resolution for Ndisplay screens rendered with movie render queue, rendering artifacts appear as vertical light/dark banding.
Resolution for a single screen threshold is around 7300 x 4132 where the banding starts to appear. Higher resolutions beyond this threshold produce an increased number of vertical artifact bands, which appear as lighter output.

Tested on several systems with either M3070ti, 3080, 3090ti or A6000 gpus using 5.1.0 & 5.1.1 and confirmed by a 3rd party. The issue is present on all versions and gpus in different projects.
