This is because the button is rendered using an image, that include the "actual" button and the engraved effect. Take a look at /usr/share/themes/Radiance/metacity-1 directory.
I've to say that this is a really really bad choice for a metacity theme, 'cause it forces you to use the order chosen by the theme creator. Metacity, instead is more flexible, allowing to move buttons in desired location, or add spacers. Here is attached a comparison between Lucid default (max, min, close), Karmic default (min, max, close) and a custom one using spacer. Only the fist one have a proper appearance, but a well behaving theme should act fine in all button layouts -- Lucid Radiance theme title bar buttons don't look right https://bugs.launchpad.net/bugs/532456 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
