I'm on 6.0a SR-5 and Yosemite 10.10.1 including today's security update. I am still encountering library display and scaling issues as illustrated below. The white space has reappeared round the outside of the Library display, and in the example below, I clicked on the bottom book in the list but the book shown was selected. I've got program scaling set at 100% (I changed it from 90% to see if the scaling issues went away)
