Public bug reported: Binary package hint: compiz
When using Google Chrome (12.0.733.0 dev) to report a bug on the GNOME bugzilla tracker, I noticed that when expanding a drop-down menu on the page, objects (such as buttons and links) which should be behind the opaque drop-down list would sometimes become visible (come to the front of the screen) and after closing such a menu, there would often be an outline of the menu left behind on the screen as an artefact. I have attached a video screencast of the problem. This is unlikely to be a problem with Google Chrome as I am having similar issues in other applications (see also: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/756560 and https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/755882).
