rain rendering issues

[Lagoonn]

When picking up an item while it is raining, and at random intervals as well I believe, puddles / water ripple effects on water surface render as black textures. Looks like, but is probably not, a z-fighting issue where the puddle textures are clipping into the water textures at times, but it makes no sense that picking up an item would trigger this if so.

original messages are all over, first noticed all the way back in like... January?

nothing to do with my configs, it happens without shaders
