Bug: Scaling error

[torxx]

Hello
Thanks for the new version!

I observe a scaling error in a special case:
My screen resolution is 1920 x 1080
The image is 1800 x 1800 pixels.
If displayed fullscreen with "Fit image to window, large only", i see a horizontal and a vertical black line within the image.

This problem is not new in 0.53, i observed it in 0.51 as well.

Regards,
torxx

Additional info:

I can reproduce the black (= background color) lines on most images: they must be scaled to 48%, 60%, 75% or 96%.

Only the 32 bit Version of XnViewMP seems to be affected.

I experienced the same bug in the MP x64-version.
Image resolution is 1158 to 1077, scale is 88%.

So far only noticed it with this exact resolution with any format with the below added set of elements.

I have this problem as well, and it seems that when viewing certain resolutions you can get vertical and/or horizontal black lines:

For example, I created this 1690x2450 blank image:

When I view it in full screen mode on my 1920x1200 monitor I get a horizontal black line:

You can also get vertical lines at some resolutions.

This is a known bug.
