Interaction Icon is being slightly stretched

Tim

Hi Folks,

Its my first time here so please go easy on me if I
breach etiquette. 

I’m experimenting at the moment with different interaction icons and I've
got a small issue with our icons being slightly stretched. My
icon is animated and the sprite sheet is just two frames on a 512x128
sheet. 

Rendering is set to software, it’s in a .png format and Its
set up like this in the Inspector:

Texture type: Cursor

Wrap Mode: Clamp:

Filter Mode: trilinear

Here is the sprite sheet:



And here's a screen grab of the stretching:
