pictures display pixelated sometimes.

I am trying to find out about the issue I am having with indesign displaying the pics as corrupt or pixelated. when it occurs If I switch between views
one view will display it properly and the other as pixelated and corrupt. To fix it all i have to do is move it slightly. But I shouldn't have to do that.
Does anyone know why this is occurring if it is a software glitch or maybe a hardware memory related problem. Im using Indesign CC 2017 version, and the latest Macbook Pro touch bar, Sierra 10.12.2
attached is an example of the image preview corrupting. There is nothing wrong with the image, just the way it displays is not good.
thanks
