Grass texture issue in LumenRT Connect Edition - Update 2

Hi there,

I am experiencing an issue with the 3D grass texture in LumenRT. It looks fine when I am in editing mode, but after I render a video I notice the grass texture momentarily disappears as I approach/move away from a grass area in the video. I have the same issue with each of the grass textures (e.g. 5cm, 10cm and 15cm). Has anyone else experienced this and found a solution? 

Regards,

Matt
