I believe this bug is somehow related to a change in gnome- panel_1:2.29.5.1-0ubuntu1 when the building of applets as shared libraries was deactivated (they are now build as standalone executables)
Changelog: http://changelogs.ubuntu.com/changelogs/pool/main/g/gnome-panel/gnome-panel_2.30.0-0ubuntu1/changelog * debian/rules: - don't build in process applets during the unstable cycle so crash issues should be easier to debug and reported on the corresponding binary It seems to me that due to this change, the notification area icons get the background of the program's main window instead of the panel's background. Compiling gnome-panel with '--with-in-process-applets=notification-area' in debian/rules (and no other changes), fixes this bug for me. I have uploaded modified gnome-panel packages to my PPA: https://launchpad.net/~cyfex/+archive/ppa in case others want to try this (you need gnome-panel and gnome-panel-data; killall bonobo- activation-server and gnome-panel after installation) -- Notification area icon wrongly rendered/uses bg_color as a background (multiple apps) https://bugs.launchpad.net/bugs/403135 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
