It looks like it's the "dreamyzoom" transition? It happened in multiple places, so I'd guess that it's not just one specific instance of the transition which is problematic but the way the transition is coded.

One instance is at the end of chapter 2 in the transition from the ending scene to the chapter summary.

If you're using the Skip function (Ctrl or Tab), it doesn't trigger because I believe that skips transitions, so you have to get to that point and click through normally to trigger the bug.
