Button Texture Issues??

I created a button texture that uses an alpha channel to get rounded edges. It works just fine when I use it on big buttons but when I apply it to a smaller button it doesn’t look right at all around the edges, even after building the game it still looks the same. I used a .TIFF format if that makes any difference. Any ideas for why this could be happening would be greatly appreciated!

you should use GUISkin that supports borders that are not affected by scale. it will let you make your texture looks in 1:1 scale at borders and scale only in the middle.
