Could the focusing screen be misaligned?

I have a feeling that the focusing screen on my K-3 III is not properly aligned.

When I manually focus as well as I can, say on a tree in a distance, and then take the shot, the tree is not focused properly. I tried this several times and I tried to adjust the dioptric compensation but nothing helps.

If I use AF, the focus is perfect with the same lens. But I can then see that I can make it appear even sharper in the OVF by manually refocusing.

I don't experience any of this on my older K-1.

Anyone ever had a similar experience? I'm going to send the camera to a service.. but I'm interested to know if this is a common problem and to know what could be causing it. Is it the screen? Or the mirror?

Best,

M
