The spacing of score elements in the document window has changed slightly between 3.5.2 and the 3.6RC, although nothing has changed in the "Measure" dialog.
You can see it clearly if you flick between the two attached pdfs. Though small, it's enough to break some systems established in 3.5.2. Could it be something to do with the increase in stem length in the eighth note in measure 2?
