The water when using vibrant visuals shows black artefacts at the edge of the render distance. This happens only when the water does not have anything behind it so it mainly appears with large bodies of water. I’ve seen it in a few far away waterfalls as well.
Graphics card used is NVIDIA GeForce RTX 5080. Seen a reddit post with other people using 50 series cards reporting the same issue so it looks to be something related to just them. This is present since the earlier previews and remains the same even with the latest hotfix.
Tried reinstalling latest graphics drivers as well as Minecraft, but issue remains.
