Thanks for the screenshot , found where the problem was. The bug arises when the user has Visual Effects set to "none" or is using only metacity as the window manager, instead of compiz
To fix this : 1: we need 2 new button pixmaps for the inactive windows [button_close_prelight_unfocused.png, button_close_normal_unfocused.png] 2: In /usr/share/themes/Ambiance/metacity-1/metacity-theme-1.xml ln 206 , this is what we currently have: <draw_ops name="button_close_inactive_prelight"> <image filename="button_close_prelight.png" x="0" y="1" width="object_width" height="object_height"/> ln 212 , this is what we currently have: <draw_ops name="button_close_inactive"> <image filename="button_close_normal.png" x="0" y="1" width="object_width" height="object_height"/> should be changed to: <draw_ops name="button_close_inactive_prelight"> <image filename="button_close_prelight_unfocused.png" x="0" y="1" width="object_width" height="object_height"/> <draw_ops name="button_close_inactive"> <image filename="button_close_normal_unfocused.png" x="0" y="1" width="object_width" height="object_height"/> ** Changed in: light-themes (Ubuntu) Importance: Undecided => Medium ** Changed in: light-themes (Ubuntu) Status: New => Triaged ** Changed in: light-themes (Ubuntu) Importance: Medium => High -- [ambiance] dialog's "Close" button not visually deactivated on loss of focus https://bugs.launchpad.net/bugs/535134 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
