I have possible repro info related to this on this related bug https://bugs.mojang.com/browse/REALMS-12160?filter=-8&jql=text%20~%20%22Cart%22%20AND%20updated%20%3E%3D%20-1w%20order%20by%20updated%20DESC
MCPE-185643 seems to be the same issue
I'm seeing the exact same behavior on 41 different minecarts in my build. The minecart stopped at a specific point in a power rail, acting as if the rail is unpowered - even if it's a power rail that is sitting on top of a Redstone block and lit red. Removing and pushing a new minecart will cause the rail to stop again at the exact same point. Breaking the rail and replacing the rail, then replacing the minecart, also has the exact same stuck locations The location of breakage changed between the update right after the realm breaking and the update on September 3rd. I have also seen this issue in the nether, but the following description is for the overworld on 1.21.23, Xbox Series X, and I've seen this in the realm and on local copies. My seed is -77107740, and the chunks covered In this update are from around the time end cities were added to the game. This is pure vanilla Minecraft survival with no packs or add-ons.
Chunks seem to matter, I have my build chunk aligned with zero minecarts crossing chunks. My tower goes from bedrock to 320, with many machines in the same chunk slice - Y doesn't seem to matter for this issue.
The chunk covered by x -23962 z -12203 is affected the most, I'd guess about 80% of carts are affected. -23962, -12203 is affected the least, with all minecarts still functional. The chunk covered by -23962, -12215 is about half affected.
Edit: I just tried loading a pre-realm-break backup locally and the carts still worked. It's possible the source of the issue is realm specific. I'll update this note if I notice anything else.
Edit 2: I copied down my realm and I was able to get the minecarts moving locally. The immobile carts bug seems to currently be realms only. My gamertag is f, feel free to pull down my realm.
Steps to reproduce
1. Spin in a circle and screen capture while spinning
Observed results:
Note the overall screen is blurry do to motion blur
Expected results:
The screen should be as crisp and clear as standing still. No option exists to make this happen.
I cannot give you an image of step 1 due to my current controller capture limitation, but am 100% sure this is happening. It is very distinct.
The movement is actual, not visual. I had to dig down and find all armor stands, which broke and dropped items once rescued from stone. As armor stands are also affected by gravity, they'll fall farther to the ground if moving down moves them into air blocks.
