I'm not sure if it's a bug, or just how it works. I created a Quick Backdrop. Set it to Motif. Imported a Black, White, and Gray image. I set the transparent color to Bright Green (because I don't want a portion of it to be transparent). Everything works good so far. But as soon as I set the Border to 1 or more, the entire Black portion of the image is Transparent.

bug... or no bug?
