Virtual texture streaming and movie render queue

I’m having an issue where textures (all set to virtual texture streaming) are not loading in some areas when rendering out an animation. It doesn’t occur all the time but I can’t find a way around it. The texture streaming settings in the ‘game overrides’ don’t seem to help (I guess they aren’t for virtual textures). Has anyone come across this or found a solution to it?

For an example of the problem see the front edge of the table in this shot.
