Hey everyone! This is my first post on this community :)

I can talk about the issue but I think this screenshot says enough. I used to have this line by itself with no "gliss." text but the line was very difficult to see through all that mess, even with the text it is still hard to see. I have seen scores where people have been able to block out a little tiny bit of the background (bar lines, time sigs and key sigs) so lines like this can be clear, how can I do that?
