I have sometimes noticed this problem, but I rather think it's a problem of Ghostview/gv. Restarting Ghostview usually helps as a last resort. However, I've got the impression that if usually happens when I switch window so quickly that the gv window comes in focus before dvips has finished its job, so the .ps file isn't complete.

I don't think this is a LilyPond bug but I thought I would mention it here.
A few days ago I was working on some LilyPond project I have. I usually
have Ghostveiw running, and set to "watch file" so I'll see my changes
right away. Well, at one point I saw some very unpleasant changes. Note heads, clefs, key signatures, maybe some other stuff as well,
disappeared. I saw some little tiny glyph in the area where I should
have been seeing a key signarture and wondered what was there. I
magnified it, and to my surprise, in the magnification window it looked
fine. I printed the page and there were no missing symbols. Then I
discovered that if I changed the overall page magnification it would
"fix" itself. I further discovered that if I toggle between "natural
size" and "pixel based" it will also fix itself. It's not that one or
the other is more reliable. It is simply the act of switching that will
fix it. I have tried saving the file when it appears strange, but the
saved file looks fine, too.
Sometimes the "wrong" appearance is fairly subtle; missing tuplet numbers and some dynamic markings, for example. At other times, though, it is quite shocking. Most of the music symbols are gone. There are staves, beams, stems, barlines, and some \number style numbers apparently substituting for some note heads, and nothing else. All I have to do is toggle between natural size/pixel based and it's fine.
As I said, it isn't possible to print out the appearance. It's fine
when printed. If I knew how to do a screen shot I'd try to get one to
send in if anyone is interested. It doesn't seem to be a real problem. Just an odd minor inconvenience.
