I've downloaded your image and tried out in XnView MP 0.99.7 on Windows 10. The image is displayed without white line, see below.

I've tried to reproduce the problem by changing various XnView settings (Tools >> Setting | Category View > View) but without success, i.e. no white line. I suspect that Windows does some anti-aliasing to improve screen quality.

- Could you perhaps change your scaling to 100% and then see whether the problem persists?
- Which version of XnView MP do you use?
- Could you please take a screenshot of your settings in Tools >> Settings | Category "View" | Tab "View" and post it here?

No, just confirmed it's (another) bug related to UI scaling

0.99.7

It's not related to that

No, just confirmed it's (another) bug related to UI scaling ...

Does this mean that the problem no longer occurs if you set your UI scaling to 100%?

which font scaling do you use?

This bug is still not fixed in 1.0

I have the same problem when cropping .png files. My system scale is 125%, I use second monitor with 1440p resolution.
XnViewMP v.1.5.0.

White line at the bottom of cropped PNGs by rogi

This is the same as my reported bug "artifacts when viewing with hq algorithms":
viewtopic.php?f=62&t=45677

The same gray bar at the bottom of the image is due to the use of scaling.
I think if the common cause of the gray bar on the bottom is fixed, a lot of the bugs associated with the bar will also disappear.
