why does K-5 II playback mode image expand

When I view an image in playback mode on my monitor, it seems to expand by just a fraction. I don't have the zoom function activated in playback mode, so that is not the problem. The image will appear on the LCD monitor and a fraction of a second later will expand by just a fraction ?

I think I may have noticed something similar on my K-3. As the image is forming, it appears to "firm-up" and pop just a smidge bigger just as it finishes. I have taken that behavior to be a side-effect of progressive JPEG loading. It is much more noticeable for images with rippling water.

Exactly... it doesn't expand, it sharpens as the JPEG is fully decompressed.

All images captured has a small thumbnail embedded and I believe this is displayed first before the full image is loaded.
In raw images it might be two jpg images embedded in the raw data, one small thumbnail and one larger that is used for preview of the image on the LCD.
