Strange phenomenon when scrolling through develop module images in LR6

Question

I just upgraded to LR6 and so far like what I see as far as performance increases.
Noticed a strange phenomenon today while scrolling through the images in the develop module. These are all rendered images with a preset applied to them.
I notice when I use the arrow key to go to the next image, the image first displays very "flat" or basic and then the rendered image appears a second or two later. If I scroll back the image displays normal rendered.
It is only when I go about 2-3 images back it starts to display the same issue of non-rendered to then a rendered image. If I scroll forward to images I have not seen yet it does the same thing of showing a non-rendered image to a rendered image.
I think I narrowed this down to the "Use the graphics processor" option. If I turn this off  the image loads a lot slower but only displays the rendered version and not the flat and then rendered version.
Turning the GPU option back on immediately does the dual image version. Strange and hard to explain but not sure if anyone else has seen this.
