The easy solution is to change the following in Compiz: window-decoration -> shaduw = "!(type=Dock)" (see attachment, which in Dutch if you don't understand). Personally this made me happy, since I do not like the shadow of the upper panel. As you might have figured out, the actual bug is not fixed with this cover-action.
Maybe interesting: If I change anything in this screen, the shadow disappears (in other words: is built up with the current information about the windows). This tells me Compiz is not updated correctly when dock-windows get a different state. Messed up listener? ** Attachment added: "Compiz - configuration of window-decoration" http://launchpadlibrarian.net/32520450/CompizConfig%20shadow.png -- Shadow remains after window closed https://bugs.launchpad.net/bugs/152264 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
