Thanks for your explanation.

According to this post it only "works if desktop alpha is turned off". And this is not the case here because I must have desktop alpha turned on! Always. Anything related to alpha desktop being off is not important do my skin. Also you mentioned cutting of parts of the image: the background of my label image is transparent, so cutting of parts of it makes no change here.

I must add that those areas which appear during the rotation are "linked" to the position of the circle - because they change shape/size while the label rotates. Hence I am still convinced it is a bug within the Skinning Engine, which creates those edges.
