Welcome …what version are you using…
The center preview and the navigation preview don’t use the same pipeline… I will have to get a link for you on the different previews in DT… 4.8 has introduced the use of the full image data preview that previously was only used during export and could lead to a mismatch there at times before it was available… if you are in 4.8 try toggling it on … it will be slow so you might not want to leave it on… this might show a better match…the ground truth is 100% zoom…
