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). See attached shot of musescore window.

I had seen the post 38151. It may be related, but is not a duplicate: I also see the phenomenon shown in 38151's animation (some staff lines/bar lines get partially overdrawn seemingly in bold face). What I am reporting is (to me) much more annoying; there are spurious lines in the gray area outside the score sub-window, often obscuring the various palettes. Please see the screen shot attached to my post.
