Entering certain chunks causes FPS drops
Entering certain chunks from West to East (towards positive X) along the Z axis causes a lag spike.
I apologize for the lack of information, but I'm uncertain of the conditions that cause this. Playing this world regenerated with the same seed offline does not reproduce the bug.
Edit: This bug doesn't seem to only happen when moving +X. It now occurs with random chunks and directions. Again, I have no idea what the conditions are for causing this.

It's a (client-side) light engine performance issue, you (probably) can't fix it on the server.
Thank you for your report!

We cannot accept any tickets with mods installed, I'm sorry. Especially if you're filing a performance issue and using OptiFine.
You might be interested in this ticket though: MC-158672. It's about a similar case where the game stutters when entering certain chunks.
I didn't see any stutters in the vanilla video previously, so I assumed it was just Optifine. Had to take a closer look.
I've linked this ticket to MC-158672, which is about the same issue. Feel free to leave a vote and/or any additional information there.
Hmm, I can reproduce this in singleplayer with render distance 12, no matter whether the block is placed or not. That chunk border seems to cause lag in general. I tested it in 19w39a as well, so it can't be MC-158672.
I believe this might have something to do with light calculations across chunk borders, but I'm not too sure.
Thank you for your report!

I am also experiencing this bug.
Commenting to say that this issue was supposedly resolved in previous version 19w39a: MC-158672
Maybe another update rolled back whatever fix they had then?
Thank you for your report!
However, this issue is Invalid.
Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.

I forgot to mention that restarting seems to temporarily fix the issue. Maybe another program causes this?
Hmm. I can confirm that there's a medium to massive massive lag spike when entering that chunk, especially when coming from that cave-ish room.
Generally, when crossing chunk borders in that world, there seems to be a lag spike.
Disabling the BlingEdit data pack doesn't seem to change anything.
What exactly causes this lag I couldn't find out due to
MC-158870.Is there anything else I should do to help? Or do I just kinda hang tight?
Hi I also have the same issue you can see i have reported it to (https://bugs.mojang.com/browse/MC-160284) but anyway heres a little wierd ting, it seem when i run and hold the jump button, the game doesnt have lag spikes. kinda wierd
What Sindre-Elias said isn't completely true, though thanks to his comment I found a new behavior.
When traveling more than one chunk away from the bugged chunk border, frame drops do not occur after one crossing. However, every subsequent crossing causes the frame drop bug.
Footage of this new behavior: https://www.youtube.com/watch?v=HXuN5M0fEo0
As illustrated in my issue (
MC-161807), this isn't limited to AMD GPUs, or CPUs - I'm experiencing this with an Intel CPU, and an NVIDIA GPU - it's not a very severe stutter I'm experiencing, but it's definitely noticeable.I'm experiencing something similar but not so extreme. Do you happen to have blocks placed 10 or more chunks away that are above Y96 in the spawn chunks? That seems to be what causes a similar stutter for me. Whether our issues are related or not, I don't know but figured I'd ask!
I am experiencing this lovely problem myself with and without using OptiFine, messing with Minecraft/OptiFine settings, ram allocation, GPU settings, etc; I have 2080 ti and a i7-8700k processor and get this when crossing any chunk in general whether it is in a new or old world. It would be wonderful if 1.14 got this fix since 1.15 doesn't officially come out until "before the holidays".
I am also experiencing this on my Minecraft server, there are like 40 chunks where this issue occurs, every time I step in any of those chunks my game freezes. Currently playing on 1.14.4, this issue didn't occur before 4 hours ago and my server is opened for 3 days. I really hope this is fixed for 1.15
Hi! checking in from 1.15.2, we have this exact issue on our server. Normally hosted and Vanilla,
For us it's actually a big old square of chunks. seems to be about 33x37 chunks big, entering from outside these chunks looks just like the author's video.
Essentialy lag spike when you enter chunk, go back further and forward again, no spike. but go back one chunk over the spiked chunk wall and back again, boom, spike.
Really odd issue, our "walls" seems to be at chunk xyz: X-665, Z-51, X-631, Z-13. draw a line between these chunks and you have the chunk spike square
Checking back in from 2020 1.15.2. I have about a 20x20 Chunk Square that causes lag when you enter, place about 10 blocks or every 10 seconds. The issue is on all brands of CPUs and GPUs as well as ram allocation. Tried solving with external means (spigot/bukkit) tho this issue is consist throughout the forks and versions
This bug is happening to me as well, using both the vanilla client and OptiFine, and using vanilla server software and Paper. This only happens when another player is in a "bad" chunk as I show in this video:
https://youtu.be/4KWEhn3y-rw
Also, it doesn't appear to be strictly an FPS or render issue, as other players actually see the stuttering player rubber band. Watch my friend rubberband going back and forth through a chunk border in this video:
https://youtu.be/3-rpttcUIm4
We reduced the RAM allocated to the server and that didn't fix it.
Happens on 1.15.2 vanilla and Paper as well, it's been present since at least 1.14.4.
Jfarf_Gl, please create a new ticket and include as much information as possible.
E: We actually already have a ticket for this in 1.15.2:
