I am using Fluxbox 1.3.2 with true transparency enabled using xcompmgr rendering. Every time I connect to fluxbox, the toolbar is not well displayed. See http://i.imgur.com/u8Pdr.png for a screen caption. To counter this drawback, I have to move the toolbar on another location and then moving it back to its initial location. See http://i.imgur.com/8Q9FP.png for an example. You will notice that empty gap on the right of the icons in the notification area. I correct it by reconfiguring Fb.
