The problem is that the clipRegion() for the image is being incorrectly returned, because _clipMask is being incorrectly calculated.

In turn _clipMask is incorrectly calculated as KstViewPicture::transparent() is returning false and so the KstViewObject::paintSelf() code is filling in the entire geometry of the image. This results in a clipRegion() which is the entire area of the image, instead of only its non-transparent area.

And finally, this occurs because _iCache is not valid immediately after hitting the Ok button in the edit dialog, so _iCache.hasAlphaBuffer() will return false in such conditions.
