Steam Class 700 Frozen Windows

Hello, I hadn't used the CLass 700 in years, but went to give it a go on the renewed East Coastway, and the front window had a frozen texture on it. I assume (and have read elsewhere) that this is likely a mod conflict, but as far as I know I don't have any Class 700 mods. Has anyone encountered this and can they point me toward what mods could be conflicting before I go looking for a mod needle in a haystack?

Thanks

 

Think there is an old cab view modifier mod that does this.

 

Try to remove this mod for the class 700... Likely this will solve the problem...
