it's normal if you have 'adjust zoom if X/Y DPI...'

there are 2 issues:
  • Browser preview - messed thumbnail if x/y DPI are not equal
  • Viewer thumbnail - messed for some regular .gifs
    1. try to save attached .jpg as .gif with XnViewMP 1.4.0b2
    test_jpg.zip
    (84.57 KiB) Downloaded 72 times
    2. close and open new .gif file
    thumbnail will be messed in Viewer

    File can be fixed though if Resize Image dialog opened with default dettings and pressed OK.
    Works if Method is not: Nearest Neighbour, Billinear
