Your textures seem to be mixed, I would suggest making sure they are properly in place.
This has been an issue since either redstone or slabs were added (whichever was added last) however, the signal shall still transmit between the blocks.
I too am having this issue, (any attempt at photography won't work) the only consistency is that the leaves are generated in a snowy biome.
sorry for the redundancy, i had no idea how to search this
not a bug dude
Shaders are very taxing on the cpu, so the graphics card, the processor, and the RAM are all being taxed. Try playing without the Shader, and if the problem persists then its an issue with the game, if not then this kind of an issue would best be resolved by posting it on the forum for Sildurs. If Sildurs doesn't have a forum, then you could try to post it on reddit to see if someone from the reddit/minecraft community would know how to help.
When a world seems to be missing, try to find it by searching your files, there should be a world folder within the Minecraft folder(I'm not sure exactly where) and in there you should be able to find the world. if you were unable to find the world, then that may be why it has disappeared.
there is very little parody between Java and Bedrock, so it may be that in bedrock filling a bottle sounds like filling a bucket
