I am not sure if I understand right, but I mean the embedded EXIF-Thumbnail that is used in the Browser with "View -> View as -> Thumbnails and Labels". As far as I understand it the thumbnail displayed there is the embedded EXIF-thumbnail when I have the option
Use embedded set and the option
Create thumbnail from original imageif embedded is smaller thant thumbnail size unchecked.
Now as you can see in the screenshot the size of this thumbnail differs between "03 Portrait.jpg" and "04 Portrait Saved.jpg". The latter image ("04 Portrait Saved.jpg") was created by opening "03 Portrait.jpg" and saving it as jpg. The new image "04 Portrait Saved.jpg" obviously has an embedded thumbnail that is smaller than the original thumb.
When I save a landscape-format image this does not occur (as you can see in the first image row with "01 Landscape.jpg" (the original) and "02 Landscape Saved.jpg" (the "save as" copy).
To clarify the problem maybe I should add: when I do "JPEG Lossless -> rotate based on exif value" first (so it is a "real" portrait image, not a landscape image that xnview rotates while displaying) and the I save this image as a new image the thumbnail size is correct!
