Some of my sheet music appears like this in Preview:
As you can see some of the lines are missing. If I zoom in then they are displayed correctly but then I can't see a lot of the score at once. I have tried different settings and it doesn't make a difference. When I open the files in Chrome they display fine. It's not just one file, many sheet music files are like this.
Any ideas?
