Vibrant 1.50 & 1.51 rain is broken.

[Smasher277]

When I use the Vibrant Shaders (1.50 and 1.51) the rain is not rendered properly, making it hard to see and forcing me to switch to another shader when it rains. I don't experience this issue on any other shader, not even Enhanced Default.

Here are some screenshots:

Is there any other information I can give that could help?

Here's another screenshot that shows more of what I mean by it being hard to see when it rains.
