The left side of my menubar has an issue in which a thin bar of it is not displaying the correct pixels. It is definitely software based as my mouse will go over it and display correctly. I can still click on the icons beneath but cannot see exactly what they are as the top half of the letters is cut off. Making the menubar translucent does nothing as well as changing the screen resolution. It is the same number of pixels according to OSX so I think that it is deep within the software. I recently reset to Lion after trying Mountain Lion using Carbon Copy Cloner. Everything else seems to be working right, however.
Here is a screenshot of it.
