(same comment as in MCPE-110518)
I have the same type of artifacts as shown in the attached screenshot. They started to appear with the 1.16.200 update.
Initially the main menu was missing when I started Minecraft, so I could not enter a game. Then I updated to the latest AMD graphics drivers and started Minecraft from the AMD Radeon Software. I could then see the main menu and enter a game, but I frequently (with just seconds in between when moving around) get artifacts as in the attached screenshot.
I use the following HW:
Laptop: ASUS X555D
CPU: AMD A10-8700P Radeon R6, 10 Compute Cores 4C+6G, RAM 8 GB
GPU1: AMD Radeon R6 Graphics VRAM1 1024 MB, DDR3 667 MHz
GPU2: AMD Radeon R6 M340DX VRAM2 2048 MB, DDR3 900 MHz
Radeon Software-version 20.12.1 (2020.1204.0703.12704) (from 2020-12-04)
Driver version: 20.45.01.28-201204a-361901C-RadeonSoftwareAdrenalin2020

Three times the last two weeks players on my Bedrock server has suffered damage when going through the same portal from Nether to Overworld. The damage happened when the "building world" screen was visible. In two cases about 4 hearts of damage was done, and in the last occasion the player died and all of the stuff in the inventory just disappeared (which was a bit frustrating when all weapons, tools and armor were fully enchanted and made of Netherite).
On several occasions in the last past weeks (perhaps after upgrading to 1.16.210?) users who entered the same portal (as mentioned above) from the Overworld to the Nether, ended up in a completely different place in Nether (far north). When going back to the Overworld through the freshly created portal the users ended up about 16000 blocks north about 1000 blocks east from the original portal in Overworld coordinates.
Something seems to be broken with the portals lately. We have not had any such issues before the last couple of weeks.
To me this bug should be given high priority, since it completely ruins the gameplay if you don't dare do enter a portal for fear of losing everything without being able to do something about it.
Bedrock server version: 1.16.210.05
Minecraft Windows 10 client: 1.16.210
Edit from [Mod] GoldenHelmet: that's MCPE-115933, not this issue.
