Can confirm

Came here to report this. Can confirm this issue.

Confirming. I have not had a crash due to this issue, so no crash report to show? It's simply lag spikes when walking between chunks.

Similar here, use F3-G to confirm. Every time I cross from one chunk to another the game lags. It also depends on the chunk range. At 16 Chunks it's not quite as bad as say 28 chunks.

Seems to be fixed, I can confirm, but I see a little lag spike after chopping down a tree now, its not extreme, but I think its related to the leaves despawning mechanic, which is maybe a new bug report, I'll browse through the new ones tomorrow when I have more time, if its not there, I'll try to reproduce it again and report it.

I can also confirm that this is fixed. Wp devs

Before the fix, I had a lot of lag while walking between chunks. After the fix it's been a small inconsistent spike most times. My latency when crossing chunk boarders goes up to 100-120ms (again, not as bad as before the fix, but still noticeable). But for some reason, I only get the spike if I stay in the current chunk for a few seconds. Going back and forth between the boarder quickly doesn't give me any lag.

Is this another bug like MC-132135 or MC-123584?
