Annoying new 2017 SP1 graphical stutter (clicking between commands)??

Any size model, when clicking thru set views (front->side->top etc) there seems to be this new "preview" stutter (repeats the image and then instantly flashes away).  I have reset all option back to default setting. No luck.  It's got to be a simple check box somewhere.

Any idea on this recent issue?
