Ok I think I understand the problem. It seems to be to do with Window decoration. In Emerald you have the ability to adjust the height of the titlebar. I noticed that the taller you made titlebar, the higher the Whisker Menu and the datetime calender were elevated. Likewise, making the titlebar less tall reduced the elevation. Disabling the window decoration plugin completely eliminated the elevation.
My conclusion is that Compiz needs to be told that windows of type panel cannot be decorated under any circumstances. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1419346 Title: mintMenu and MATE Menu are elevated/offset by compiz To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1419346/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
