Burndown list for an beta release:

• Fix annoying crosshair/shader interaction - Appears to be an interaction with a certain resource pack
• Chunk loading order & transparency sorting

• Fog w/ shaders looks weird - @unicornbloods
• Chunk overlay (F9) not always showing

Use SeparateAO borked - fix sodium AO

Fog w/ shaders causing weirdness

Chunk loading order & transparency sorting:

Crosshair & Shaders:

AO Fix Options

1. Rewind quads, use sodium AO
2. Use FRAPI AO https://github.com/FabricMC/fabric/tree/1.20.6/fabric-renderer-indigo/src/client/java/net/fabricmc/fabric/impl/client/indigo/renderer/aocalc

This is the problematic crosshair texture from assets/minecraft/textures/gui/icons.png - from f32 modded.

Currently unclear as to why it's causing issues.

Edit: Playing around with GIMP - exporting it with Save color values from transparent pixels causes the issue, exporting it without that option set does not cause any issues.

Color value was 255, 255, 255, 0 vs 0,0,0,0 -- fixed with explicitly enabling GL_ALPHA_TEST

Going underwater with Comp v4 enabled
