I'm trying to make an icon with transparent background. The icon has the shape of a circle, but when I put the icon on my desktop, there is a square shadow around it as though it were a solid icon. Other icons with transparent backgrounds don't seem to have this problem:
I made the icon out of an svg which I edited together from different svg files in Inkscape and tried making icons out of it with different tools, such as online converters like convert.io, and also with gimp. (I also tried with paint.net and a batch file for inkscape but paint.net made the icon very pixellated and the batch file did not work for me and I don't know enough about inkscape to be able to correct it.)
At first I thought the problem was that the original shapes of the svg extended past the circle and I used Inkscape's "clip" function to crop away the rest, but then I released the clip and cropped the paths to not extend past the circle and the end result was still the same.
