It seems not to be a CSS problem but a size one's on IE (maybe in order to avoid big calculation on client browser).
The image was a big one (+2K pixel), and the problem disappears when I reduce it under 1000px.
Question
I'm looking for a way to do anti-aliasing on a rotated image with a large border on IE10 on the image above.
I've try -ms-backface-visibility:hidden
which fixes it on Chrome, but it doesn't work and I don't find any other information about IE10
