XnView Software

XnView: MP 1.3.1,1.4.0b1 64bits
OS: Windows 64bit (22H2), display resolution 3840x2160, win scaling 150%

Browser and Viewer tab Thumbnails
Incorrect thumbnails for image with different x/y DPI

To reproduce:
1. run clean portable XnViewMP
2. open atached .gif (test image has x72/y18 DPI)
ps. bugreport split from this post:
1.3.1 - displaying image with different x/y DPI

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

  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.
