At <http://www.ford.com/technology/sync/>, the title above the video is not repainted completely when switching from one video to another using the tiles below the video.
This doesn’t happen in r52939 and does happen in r53181. In between there are other plug-in compositing issues making it difficult to tell exactly when the regression occurred.

The mispaint only happens on those with text above the title ("Mobile", "Entertainment").
