I'm running slackware_64 13.37 with xfce. I just installed cairo-dock and the plugins. It's working almost as expected. I went into the config utility>Behaviour>system>Composition and set "Make the config panel transparent" and All>Visibility to "Hide the dock when it overlaps the current window" yet I still have a black box around the panel when other windows are open (
see pic).
How does one get rid of this?
