block artifacts

Artifacts from the blocks appear, mostly trees. As you can see in the screenshots, it happens that half of the tree or part of it is missing and the cut off part may be in another place in the world. water is also disappearing. I noticed that they don't appear where I usually am. it appears in all biomes. They appear everywhere all over the world. The world is 9 months old. At first I didn't see them or didn't pay attention, but then they appeared. I would really like to fix this in the existing world. I've always used a license. I do not use and have not used mods.
