Storyboard Pro 5 cutter tool jaggies

I find that when I’m cutting with the cutter tool it leaves a very jagged edge. I found that zooming way in, helps to minimize the jaggies, but they’re still there. I’ve experimented with using a graphics tablet, mouse and track pad, but the results are always the same. It’s most noticeable when I’m cutting an imported jpeg. But it’s also happening with a regular vector shape. Has anybody else found this to be a problem?

I’m using Storyboard Pro 5 on a PC.
