White border around transparent PNG export
Everytime I'm exporting a drawing from Illustrator with a transparent background I get white border around the drawing. I think I tried every solution I found online, but it's not working. The artboard is 2048x2048 and I'm exporting at 72ppi with Supersampling selected. I also alligned the artwork to the pixel grid with total numbers only. I even tried exporting from Photoshop, but without loosing a lot of quality I can't get rid of the white borders.
The following two images show the drawing in Illustrator and the image when imported onto another image.


Anyone have some new suggestions on how to fix this?
