XnView Software

XnViewMP 1.8.2 64bit
Windows11 (23H2), display resolution 3840x2160, ~139ppi, win scaling 150%

General - image scaling
few issues with image scaling
- its not consistent across Viewer and Browser thumbnails/preview
- image is cropped on the right and bottom in Browser thumbnails (maybe same QT issue)


expected behaviour
probably like following:

• win scale >100%
  • ☐ Zoom on HiDPI screen
    do not scale image anywhere (same scale as at 100% win scale)
  • ☑ Zoom on HiDPI screen
    scale image everywhere

I would also rename
Zoom on HiDPI screen: 1 image pixel equals 1 screen pixel →
Scale on HiDPI screen: 1 image pixel equals 1 screen pixel OR
HiDPI scaling (1 image pixel equals 1 screen pixel)
