XnView Software

XnViewMP 1.4.4 64bit
Windows11 (22H2), display resolution 3840x2160, win scaling 150%

Viewer - cache?
image does not updates on revisit

To reproduce:
0. have 2-3 images in folder*
1. run clean portable XnViewMP
2. open 1st images in Viewer
3. edit and save 1st image in external app (eg mspaint)
4. in xnview Viewer goto next image, than return to 1st
image will not represent changes
5. press Return to open Browser mode
thumbnail/preview will show modified image

*if you have >=4 images, than 1st images will be updated on revisit if you scroll to 3rd image.

Expected behaviour
it is absolutely OK not to update opened image live,
but I guess it shall update on revisit

UPD
disabling "Keep current image" fixes this behaviour
(Settings>View>Misc)

Preview Refresh On Live Changes to Image Data

I recognized the same thing during my work with adobe photoshop elements.
The only way to refresh the browser is to close the browser window of xnview.
Maybe it could help to view another folder and go back to the previous folder with the changed picture.

In Settings > View > misc , by disabling cache options, perhaps this "bug" will disappear ?

- "Read one image agead" and " "Keep current image"

thanks, michel038,
disabling "Keep current image" fixes this behaviour

it looks like it caches up to 3 last openned images,
if so, the proper name should be something like 'Cache last 3 images'

Thank you for the hint.
