UPDATE:
I just tried modifying the suggested code (see my first response above) to the following:
CurrentValue[$FrontEnd, {RenderingOptions, "PreferredGPU"}] = "GPU"
This WORKED! I think the software didn't know how to render the graphics until I specifically told it to use the GPU (as opposed to the software).
The default setting is "Automatic"
You can check this by just evaluating:
CurrentValue[$FrontEnd, {RenderingOptions, "PreferredGPU"}]
When I set it equal to "GPU", on a hunch, it worked. Incidentally, all of my graphics /plots now work/render much better as well. I had issues scrolling past a large graphic plot with many hundreds of thousands of points but this simple fix seems to have resolved this issue as well.
Of course, you need to have a Nvidia GPU installed on you computer for this to work.
