When Pasting a picture (2748 x 3712) in a new one (1600 x 1900 with 100 pixels/cm) with no change of the size of the destination file, when I resize the layer to have all I want visible, it crops the visible part. I can move the big picture but can't resize the layer without loosing as if it was crop. So it's impossible to use bigger picture in a smaller document without loosing a big part of the picture.
I tryed the same manipulation with the same pictures (different tests with different resolutions) on the previous stable version of Paint.net, and it works perfectly.
