Nether portal sometimes kick from the server and tp at wrong location

When passing through a nether portal, sometimes (i only experienced this on a server) your minecraft client freezes and when you log back on the server, you are at the coordinates of the portal but in the other dimension. That happens because the server doesn't have enough time to divide or multiply your coordinates by 8 before you've been kicked. On this coordinates, you can eventually see some leads. That's because everytime you pass an animal with a lead through this portal, the lead breaks, glitches and goes to this location. As a "proof" I can link a video of Mumbo Jumbo, he experienced this bug at 2 minutes : https://youtu.be/ljZmeRSPzm0

Sorry, I failed writing the title, when this bug occurs, the game doesn't crash, you're only kicked from the server with a "timed out" screen. And then when you come back, you're on the wrong coordinates. This bug also seems to appear only when my computer is a bit laggy.

Here are the server logs. I think I have a better idea of what happenned. I pass the portal, and because my pc is laggy, my minecraft freezes and doesn't load the chunks on the other side. The server wait, and because my minecraft has frozen, the server doesn't get any package from the client and he kicks me for time out. And when I log back in, I am at the same coordinates as the portal, but in the other dimension because I was kicked before the server divide or multiply my coordinates by 8.

Isn't this ticket caused by the same root cause like MC-98153 ?

migrated

Yes !! I am pretty sure that's caused by the same root. The portal seems to first tp's to his coordinates on the other dimension and then tp to the right location. But in my case because of lag I get kicked and I am stuck in the middle of nowhere (really annoying x) )

That actually made me think of another bug that occurs when you get out of a nether portal after being tp. Your player starts to rollback every time you try to run. Disconnecting and reconnecting to the server solves the problem. Maybe it's caused by this same "anti cheat" thing. I'll try to reproduce it and maybe create another issue... Have you ever heard of this one ?
