Slow image playback!

Whenever my K3 previews an image, first it shows a jagged, low quality image for about 0.2 sec and then a full, high quality one.

This problem occurs clearly when I browse through images, each one needs 0.2 sec to fully loaded, which is irritating.

This is probably not because of my card (a fast Sandisk UHS-1). Because even when I remove the card and take photo, the instant preview behaves the same way.

Aside from this problem, every other function perform very fast.

Is this normal for a K3? My camera is manufactured recently - 2014/12 - and comes with 1.11

//I have turned off everything (High ISO NR, Shadow/Highlight correction, lens correction, AA filter). The problem is still there.

The reason this happens is that it can quickly show a low quality preview and then if you want to look at it, it will load the higher quality preview. You know, so you don't have to wait for every photo you skip through. This way, you can just skip over them with the low quality previews real quick, and then when you get to the photo you want, it will load as fast as possible at the high quality. At least I assume so, I am not a Pentax engineer to guarantee anything.
Anyway, I usually just disable image preview altogether, so I can take photos faster and then I just press playback button if I want to double check something.
Oh, and regarding camera firmware, it is a good idea to use the latest firmware (it includes all previous updates and patches)

It is something I noticed today, only because the bokeh looked square -like before smoothing. At first I thought I was shooting in Small but that's not the case.
