Picture preview is blurry and doesn't refresh.

Hi,
I got this issue from couple versions of CO.
Picture is stuck in middle of refreshing and it's super annoing.
I shoot tethered with picture orientation 270, because it was vertical format.
I have this problem for many years, at least 5.
I have no idea why it happens, it's always after 200-300 pics. I got 16gb laptop to avoid this problem.

;/

Any solution?

I use CO 21 and M1 macbook pro.
