You're playing with OptiFine, that's why. Try playing without OptiFine and see how the game runs.

Is the client modded?

Unable to reproduce in 1.18.1-pre1.

The closest thing to reproducing this was setting the server’s view distance lower than the client- in which case, this works as intended per 1.18’a changelog.

Does MC-219639 describe the issue with FPS?

This is a feature request. Ice caves were more or less a bug in Bedrock Betas, and Mojang has never, ever stated that Ice Caves were an official feature. Invalid.

Does allocating 4GB of RAM or more help with this?

Invalid- the cloud height is lower and matches 1.17.1 and earlier versions, not 1.18-pre1.

Have you tried increasing the allocated RAM from 2GB to something like 4GB?
If you don't know how, it's in the installations tab, hover over the Latest snapshot, click the 3 dots and edit, then clicks More Options, scroll down, and change the 2 (in -Xmx2G) to 4 or higher. I don't know if this is the exact solution to your issue, but I had a very similar problem and doing this fixed it. I hope this helps!

There was a similar report like this a few days ago. Do you happen to be using Optifine?
If so, this would be a duplicate of MC-240733.

This happens due to the new swimming mechanics added in 1.13, where the player flips to be horizontal and swims faster.

1. Versions from 2011 aren't supported in 2021. Snapshot 21w44a and release 1.17.1 are the only versions Mojang's worried about.
2. You are apparently using Lunar Client, that also isn't supported.
3. It could've just been raining and the rain didn't render.

Mojang has also never stated that snapshot worlds are guaranteed to be supported in the future.

The bug for that issue is MC-240507

Have you tried allocating at least 3GB of RAM to Minecraft? I've noticed while playtesting that 2GB causes the game to be nearly unplayable, after allocating more RAM it's been running much smoother. I'd personally recommend 4GB allocated, but 3GB might also work.

Invalid. Modified clients have never been supported by Mojang.

Unable to reproduce.

1.18 worlds don't blend with 1.18 worlds

Mojang has repeatedly stated that worlds in old snapshots have no guarantee of being supported in future versions, especially 1.18 snapshots. They've also stated blending only works with worlds using the old terrain generation.

Bug reports from old versions aren't valid, are you able to reproduce in 1.17.1 or 21w43a?
