You are in the beta version of the game. You'll need to download Xbox Insider Hub (if you don't already have it) and deregister from the beta to play the full release of Minecraft.
This bug: MCPE-114259 may be related to this one
I tried Ready Sled Go (by Noxcrew) and boats float on that map. It may be map specific because I can't reproduce on a different world
Turning off vsync in options.txt has not helped with this issue.
Most likely related to RenderDragon.
This is most likely a Lifeboat issue and Mojang probably can't fix it, Lifeboat will
This is because you have to type "true" at the end, not "false." It will hide the particles once you put "true" at the end.
Happens in 1.16.201 hotfix.
This affects 1.16.200.
This doesn't just happen in Realms, it also happens in multiplayer games (like when you join a friend's world). It's very annoying, so please get it fixed soon! (also I'm on Windows 10 in version 1.16.100)
This does happen on Windows 10, but very rarely and If you restart Minecraft it will usually fix itself. (This is from my experience)
I can also confirm for Windows 10
The bug still happens on the latest version, 1.19.51. I attempted to replicate the bug on a singleplayer world, but it only seems to affect realms/servers. Containers, once stuck open, also appear that way to other players, and they will stay open until the player who bugged them open relogs and opens and closes the chests again. Other players can still interact with the bugged chests, but they don't play an animation.
The bug does not stop, in my testing, after opening a crafting block (as it prevents you from doing so entirely) or switching dimensions, only after relogging.
