Hm, the pulldown menu is far too transparent for my taste. That looks worse than the too transparent menus in one of the previous OS X versions (could have been Leopard) before Apple backpedaled after severe user complaints and toned down that effect.
You can turn off transparency....system pref/accessibility/display/reduce transparency...
Just installed on my macbook (late 2009 2.26 white unibody,4gb mem)..runs better then mav 10.9.4!
