- 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
- ☐ Zoom on HiDPI screen
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)
