If you set the transparency to 50% you will notice that the menus won't adapt the style adequate. It's ok when the menus highlight a bit more but the should respect the transparency settings of the panel in any case. Otherwise this looks like the view is damaged (See screenshot). Also the border of the menu is also to harsh. Maybe the lower edges should be round... There need to be some more considerations regarding this topic.
