Minecraft Beta rendering bug
Water logged dripstone admits light.
theirs already someone who talked about it but, it seems to be a problem with the water-logged rendering or the light rendering system. They could re-work one or both of the mentioned rendering system or code a patch, this is not a bug with textures as I have used and removed a texture pack and got with default textures. this is not of high priority but should be patched in a bug fix update or in the full release of the wild update. i am using a windows pc, but this bug is also on android.
