Visual glitches and "poor" performance

First of all, using a 4090 and 7800x3D with 64GB of RAM. I also used the installer to install everything for Minecraft v1.20.4.

I'm getting roughly 75-80ish FPS, which isn't a big deal, but I honestly expected a lot more out of my machine. Also using only 12 render and sim distance, with 128 LOD on Distant Horizons.

However, my main issue is with some of the visual bugs I'm seeing.

First pic I've attached is the leaf bug, where I'm seeing weird striping and lines in the distant leaves.

Second pic I've attached shows what I see whenever I try to go underground.

Visually, everything else looks great.

Yes, I'm on the latest drivers. Yes, I've restarted my PC after installing everything. Only other mod I'm using is the Tectonic datapack for world gen. No other datapacks, mods, or resource packs are in use.
