Strange Copy/Paste

[Piteur]

Hello.

I use XnViewMP 0.72. Do I see a bug? Imagine a picture; in that picture, a full hight portion (column) is selected for copying. It's copied (CTRL+C). When the selection is moved for pasting, there is a slight upward shift.

Here is a picture where I selected the right side (narrow column); then I pasted it in the middle.

>>> after pasting

This peculiarity does not occur in XnView 2.32.

Where is the problem ?

====== EDIT ======

I just installed the version 0.75 (32 bit - Xubuntu). The problem is the same...

and if you save it, always the problem?

Thank you, Pierre. But not sure I understand: look at the pictures attached to the message, they are saved files ... I swear: no special effects!

When I reopen a file like this, there are no corrections ( )...

Don't you get to reproduce the bug?

Note: when I drag several times selection from left to right (and vice versa) before CTRL + C, selection overflowing down is reduced down by 1 or 2 pixels, then pasting (CTRL + V) is right ...

You copy the right area, and after you paste it, right?
I've tried but no problem??

Exactly.

Don't understand. It's very strange...

====== EDIT ======

I try to reexplain with screenshots :

Thanks for helping.

right, it's a bug in the move of selection not paste...

Ok, the bug is identified!

You can get around the problem by "shaking" laterally the selection (using the mouse), before copying...

XnViewMP 0.76.1 (Windows) :

Solved bug, it seems. Thank you, Pierre.
