Describe the bug
For some odd reason some of the action button icons (i.e. textures) are showing up with a rigid black background. I cannot figure out what's going on for the life of me.

My initial thoughts was I could apply a mask on top of these spell/item textures to lessen the effect. It's mystery to be solved.

Please comment if you have an understanding on what's going on.

Item #1 on the image below show's the dark rigid corners (not the behavior that is expected)
Item #2 shows what should be showing

This will be fixed by setting the empty grid texture as the mask so that the square edges are rounded.
