A grey bar showed up while I was working with UTAU-Synth. It doesn't do anything when I click it, but it adds notes as if the bar doesn't exist when I use the pencil tool. It kind of looks like the thing that shows up when I make the note vibrato (though I'm not completely sure if it's supposed to work that way; the vibrato settings don't show up when I choose the option). This didn't happen before I updated to OSX Mojave...is it because I updated the operating system? I also noticed that the magnifying glass in the search bar is upside down and the window flashes more than before. It's not that big of the problem since it goes away after a while, but it's just a bit irritating.
