[gentoo-user] Window borders in gnome desktop when maximized hide behind panels

[Thanasis]

After some recent update (~x86), windows in gnome desktop when maximized 
hide their borders/bars behind the desktop panels, which is really 
annoying. In the case of terminals, the prompt gets almost hidden, in 
the case of other applications, the "file" menu gets hidden, scrollbars 
etc...
Has anyone else experienced the same problem?
