Tested on physical hardware with 19.04. The issue is still present but the viaul manifestaton is slightly different. Rather than black flickers it's more of a shading effect that flickers on and off with mouse movement. It can also be caused by enabling the option to extent the magnified contents beyond the bounds of the desktop.
