--- Comment #2 from Rico kgbricola@web.de 2008-11-20 13:01:33 --- Could you have a look at bug 10778 ?
Probably the patch there moves the border a little bit away, it doesn't solve the problem. ( I don't know if it applies to the current git ... but since it is only one line you could also change it by hand. )
