I just found out that this is triggered through toggling guake (a terminal window, an oneiric package). It appears and disappears on F12 and obviously the desktop is repainted when the window appears, but not when it disappears.
It does not appear when minimizing a window like nautilus. So it seems to be more specific to guake-like disappearing windows. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xcompmgr in Ubuntu. https://bugs.launchpad.net/bugs/835349 Title: window shadows left on wallpaper even window moved To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xcompmgr/+bug/835349/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
