KDE Compatibility issue in DockbarX

Binary package hint: compiz

There is a bug in the new Compiz version in Ubuntu 11.04 version (in GNOME classic mode) with the window previews in DockbarX. When I enable the KDE Compatibility Compiz plugin and enable the window previews in DockbarX the preview appears behind the popup which is a problem. Here is a screenshot of the issue: http://goo.gl/ha234
This used to work perfectly in older versions of Compiz and Ubuntu. It's probably a bug caused by the C++ rewrite of Compiz.
I have notified the developer of DockbarX about this but he said that it is a bug with Compiz and the only way to fix it is to contact the Compiz developers.
