Now that I've seen a picture of this, I see it, too.

However, this bug has characteristics of something I always saw in 
v2.039: I would sometimes see the spectrum sweep get "swept out" from 
right to left. It would get completely cleared, only to reappear less 
than a second later.  I never knew what caused -- I never noticed 
anything in particular caused it, though I sometimes thought it 
occurred when there was a particularly potent static crash. I was 
never bothered or much concerned by it. I've seen similar behavior 
when the spectrum display goes to all red: the white part of the 
spectrum trace is swept out from right to left, only to reappear very 
shortly afterward.
