It makes the game lag, even though I'm offline and playing solo. I've checked the heat of my console(an Xbox One)and it wasn't hot. And it happened again the following day just as soon as I joined my world. What I mean by lag , for those of you who don't know, is all of the AI stops, and actions like eating and breaking stop working right. I can still move and do all that stuff but when I go to eat it never fills my hunger. Same thing with breaking, I can break all the blocks I want to, but there won't be any particles and the block won't drop.
*Update: Just found out it only lags in the nether.*

I posted this on another bug thread, but I now feel that the bug thread I originally posted this on was unrelated.
I'm having this issue really badly on my iPad Mini 5 on 1.17.41, only in the nether. It happens pretty consistently, about every 10 seconds everything but movement just stops working for 5-10 seconds at a time.
When bridging you can suddenly end up over nothing since the blocks that you just placed didn't actually place.
I at first thought this was a server issue as this issue looks really similar to server lag, but this happens in singleplayer, with LAN and general multiplayer turned off. Same when wifi is disabled on the device. This is not a realm.
The world I have this issue on is rather large, 310.3MB. But this bug is strange because no frame drops occur whatsoever, it only effects entities and block placement/removal.

I did a small test to verify things.
I went into creative on the world with issues, verified it still happened on creative.
I turned off mob spawning and did /kill @e, tested again, no lag occurred.
Spawned about 25 piglins, no lag. /killed those.
Spawned about 25 striders, lag started occurring again.
After this I decided to make a new world to try to figure this out further. Fresh world, mob spawning off, random seed. With that I figured out these steps to reproduce. Higher end systems and lower world sizes will need to spawn more striders to get this to happen, but the process is the same.
Create a new world with mob spawning off (can be on, but having it off makes it easier to narrow down the issue), enter the nether.
Check to see if blocks break normally. If there is no block lag after breaking blocks for about 2 mins of continuous breaking, you're good.
Spawn lots of striders, amount will depend on factors such as world size and how good your computer is.
World will start to get laggy (no frame drops). Try to break blocks as you did earlier, there will be block lag.
This issue is almost certainly caused by striders.

I've done another test and have now completely verified that this only happens with baby striders riding striders. They cause the game to stop ticking randomly in short bursts while they exist. Video showing this bug is linked as a twitter vid. The redstone clock is there to show when it lags. https://twitter.com/TitaniumSp0rks/status/1458615340309565444

Striders and Ghasts seem to be broken entirely in terms of their code, as I tried using Ghasts in a multiplayer world, and it freezes up the server completely until the client kills them (either by you or command console). It is weird to see how they break the world and the nether, though.

This issue is similar to MCPE-147882 and may have the same underlying cause.
Jordan Odulio: ghasts lag is being tracked as part of the above ticket because it happens specifically when they are targeting + unable to reach navigation goals (they are unable to navigate when trapped in a boat or minecart).

Have this same issue tho I can't verify if there are any striders near by, I'm pretty high up. As well as the block breaking/placing issue, I'll swing my sword and it won't deal damage, shield activation lags, arrows fire seconds to late or not at all, as well as eating. If it is stridere, at least we know that much, and can be looked at for fixes
(P.s. To the moderators: y'all are the real mvp's. Dealing with all the complaints can be a pain but ur appreciated 🙂)

Paul Unrau: to confirm it's this issue, make a copy of your world, turn on cheats, and put /kill @e[type = strider] in a repeat command block where you are working in the nether. If that clears the lags, then this is your issue.

Affects 1.19.0.30 beta on Android device

Still affects 1.19.0.32

This happens to me too, and I had NO IDEA that it was caused by striders.
Jens, Agnes, Kingbdogz, etc., if you're reading this, fix this bug almost immediately.

My game lag but not has much (can play normally but entity teleport, with strange sound + delayed fireball from ghast) as you and only on playstation . It is the same issue/bug?
