Not a bug, feature, it's supposed to maximize windows that are "almost" maximized. It does that on window map, so switching workspaces, as well as launching the app, should maximize:
$ gconftool-2 --get /apps/metacity/general/auto_maximize_windows You can disable with: $ gconftool-2 --set --type bool /apps/metacity/general/auto_maximize_windows false ** Changed in: unity-2d (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-2d in Ubuntu.
