When playing fullscreen games I sometimes get a black background in Decent Icons. The desktop is not showing through. This doesn't always happen. Just sometimes. I have not found a pattern to it yet. The good news is that I think I might have found a solution to the bug. I think its because my Decent Icons dock is bigger than the desktop. I set it up so that the hide menu button is right in the top left corner of the screen. when I do that it means that the dock actually has negative coordinates. If I set it to positive coordinates I never get the black background. Or at least I haven't yet.
