I've been experiencing an issue with creating an icon that fits in any size and shape. I use Studio to do it, but I must be doing something wrong, because there is a small padding in it.
I add my image asset as background layer with nothing in foreground layer.
I've tried to fix it by trimming it and using huge icon source 1920*1280.
When I changed to new theme it turned out that few other apps on my phone(other devs) have same poor icons.
