[Bug 35519] Title-bar maintains rounded corner when maximizing big windows

Comment:
This is not a bug theme, I have realized this, because I have try many others themes and it also happens.
Obviously, when the theme has not round corners, seems that there is not any problem, but the right is that many themes (perhaps all) don't fill the titlebar and they leave some pixels in the right and left, when the window is as big as a maximized window.
Perhaps this is a clearlooks engine problem or a metacity problem but I don't know too much about it.
Can anyone move this bug to a correct package? 
Is possible to move a bug to another package in launchpad?
