Application Icon w/ Transparancy in Ubuntu

I’m attempting to use a texture with transparency as an icon for my project, and it works properly on all platforms but linux. In the editor, I have the same texture applied to each resolution of icon.

Once a linux build is made and run however, in Ubuntu the application icon appears broken. It looks something like this:

Am I doing something wrong here? It works on both windows and mac platforms.

Edit: I’ve tried using a .ico file instead, without transparency, and I get similar results. I’ve tried with and without using the ‘override for standalone’ options, but I can’t get my game to have an icon.

About the machine, it’s running Ubuntu 13.04 in a VMWare Player virtual machine.

This post is pretty old, but I have the same Issue… (Unity 5.3.1f1 and Ubuntu 14.04) Has somebody found a solution to this Issue?
