Can confirm 1.18.2 (and the most recent snapshot)
No, the visual glitches are entirely different. I have an old video that I took of it and I can create another with F3 screen on if needed (although it happens no matter what you do, as long as you move quickly and make a turn)
The bug in the provided issue shows stationary visual glitches, this is entirely based on the player moving causing chunks to unload.
also to note, the visual glitches are much more "orderly" and happen in a single direction in an arc, not in a bunch of random chunks not rendering. The chunks will render again, but just take a bit.
video with pie chart (and showing that it happens in all render distances, and FOVs) https://youtu.be/4XivLs7R3Ag
This bug still happens in the latest snapshot (22w11a)
This is a bedrock bug/technical issue so this should not be posted here
My discord is BiC#6921
as @Mega Charizard X said, please state your hardware (RAM, CPU) also try recording this happening with F3 up with OBS. if you want, I could add you on discord for faster communication as this is not particularly a bug with minecraft, but a bug/performance issue with your computer.
have you re-loaded the world? minecraft will sometimes not teleport ridable entities when the player dismounts. re-loading should fix this
Please classify this as a bedrock bug as it is such. People working on the java platform will not be able to help you with this.
Please classify this as a bedrock bug as it is in bedrock (PE) not Java (PC.) The bug is most likely because the IPad 4 is an old device and apple is $h!t and likes to make you buy newer devices by messing up the drivers.
Please classify this as "bedrock" as this is a bedrock bug not java
This is most likely the game having to re-render the chunks every time you turn your head, I'd say either turning down render distance or using optifine would fix this
mouse sensitivity
the number stays the same, but the game perceives it as double
Yeah, this has been a thing since beta (probably further back, but I haven't played earlier versions)
