I play modded, but tested the game with no mods or resource packs or shaders of any kind and still have the problem.

Mods/Packs:

• Mizuno's 16 CIT
• Mizuno's 16 Craft 
• Ghoulcraft
• Hananacraft 
• Mushroom Golems
• Invisible Item Frame Pack
• BSL Shader
• Optifine

All trees are Too Cubic. They're still transparent, but they're missing definition/differentiation/shape. Attached is a picture of my problem (dense forest pic) and a picture of how the leaves should look (leaves set on ground). This issue extends to vanilla leaves.

My partner said something about the alpha channel transparency being involved/not showing up? Someone else brought up that it looks like an incorrect model, but when they used Mizuno's on their end it looked fine, so it's seemingly just me.

I've done everything I can think of:

• Set all settings to Fancy, then Fast then Fancy again
• Checked all Shader settings, toggled shaders on and off
• Ran in Vanilla MC
• Ran Mizuno's+Ghoul+Hanana, then ran only Mizuno's
• Turned off all resource packs + CITS + mods
• Reset PC
