Worked: None same in 2.83
Short description of error
Geometry Node works differently for Cycles and Eevee in the World Shader Tab, The Coordinates are distorted with Eevee. Im not sure if this is as expected.
Exact steps for others to reproduce the error
1 Goto Shading Workspace
2 Enable Viewport Shading and enable World Background
3 Add Geometry Node.
4 Connect either Position, Normal, True Normal or Incoming to Background Shader.
5 Switch between Eevee and Cycles to see the difference.
On the other hand, the Normal output of the Texture Coordinate Node is exactly the same in both render engines.
