Spurious rendering of scores outside of music window
When I create/edit a score that is more than one page long, scroll from one page to another, then move the MuseScore window part-way off the screen and back on, I get spurious renderings of part of the music score and other lines in the gray areas around the actual score sub-window. These go away if I resize the window or bring another window into focus in front of the MuseScore window. This has been a problem on MuseScore 2.0 nightlies for as long as I have been trying them. It is not a problem in MuseScore 1.3. This is on a Mac running OS 10.9.5 (I also had the problem for early 2.0 nightlies on Mac OS 10.6.8, and more recently on earlier versions of 10.9).
