Blocky shading from Directional Lighting 3D & World Environment effects

Godot Version

Godot 4.5.1

Question

Tried following a tutorial that lead to combining the shading of the Directional Lighting 3Dnode and certain World Environment effects together. For some reason, when combined, the shading comes out blocky and glitchy. It will look like here: https://www.reddit.com/r/godot/comments/1s82yal/blocky_shading_from_directional_light_3d_world/ How do I fix this issue?

Could you tell more about your system and GPU? That could be a problem with your driver.
Which renderer do you use?

Well, I have a custom computer I made in 2020. It’s a Ryzen 7 with 16 GB of ram with a Radeon RX 580 graphics card. I haven’t updated it myself in a while so maybe I could try. Renderer? You mean Forward+? That’s what I used.
