Recording has black screen after switching screen shares

We recorded a session where two individuals shared their screens. On the recording, at the point of hand off, the screen goes black. The audio continues and you can see the cursor moving as the speaker clicks on things on their screen but the screen is completely black. However - and this is realy weird - if you pause playback and then continue (hit pause, then hit play), the screen share suddenly appears as if nothing was wrong. It happens every time you replay it, it will be black until you pause and hit play, then suddenly it works fine. Any ideas what we can do to fix this?
