I am a musician and when on my Mac, I use Sibelius to make scores. I export them to pdf to e-mail them to my bandmembers and so on.
Since updating to Quantal Quetzal two days ago on my main computer, I came up with a curious problem. The pdfs are rendered horribly and are hardly recognisable as scores anymore. It happens in every pdf reader I can use in Ubuntu, so it's not a bug in evince or something, I guess. It also happens on my mother's laptop where Quantal is also installed. I've got an example attached so you can see what I mean.
I don't know against which package I can file a bug. Is there a specific pdf rendering package connected to Quantal?
The examples are saved in jpg in Gimp (in Ubuntu and in Mac OS X). The Mac one is the one how it's supposed to look like. I've saved them without any modifications. They look like this in a pdf viewer as well.
Thanks for your help.
