I found this "bug" recently, and discussed it with someone in #gimp on the GNOME IRC, who helpfully pointed out that this was due to the toolbox and other dialogs being hinted by the window manager as Utility windows. This is configurable in the Preferences, under the Window Manager heading, with dropdown boxes to choose the window manager hinting.
The default behavior is "questionable" and a bit confusing, but this is not a bug. In short, to change in order to get expected behavior: 1. Open Edit Menu 2. Go to Preferences 3. Go to the Window Management section on the left. 4. On the right, examine the dropdown boxes under the Window Manager Hints heading, and select Normal Window for it to be treated as a window. 5. Restart the GIMP. ** Changed in: gimp (Ubuntu) Status: Triaged => Opinion -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/288461 Title: gimp menus always on top of images To manage notifications about this bug go to: https://bugs.launchpad.net/gimp/+bug/288461/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
