TrainGlass.fx Shader Problem

I've been working on trying to get some glass insulators for my telegraph poles and I came across a weird problem.
In this first picture is what it looks like as I place the pole onto the world editor. All is well...
Then I go and set the time in the scenario editor and save. Look to what happens to the insulators. They seem to get blurry.
Is this a bug? Can it be fixed?
