I am working on a custom sized project (980x408). I don't think the custom size is significant, as I worked on a custom size of 980x400 before this, and didn't experience the same issue.

I have tried this with a few different transitions and I am now always seeing this issue. Here's a link to a short clip with a transition so that you can see what I mean:
