Heavy snowfall and rainfall are broken

Wind speed set to 20 for both snow and rain weather, snow ripples are enabled, OpenMW:

heavy_snowfall

heavy_rainfall

For some reason the raindrops/snow ripples don't show up on water and the particles act weird, Wind direction is still correct though and NPCs block with their hands as expected.

Morrowind for reference:

Snowfall, heavy: heavy_snowfall_mw

Vanilla value: slow_snowfall_mw

Rainfall, heavy: heavy_rainfall_mw

Vanilla value: slow_rainfall_mw
