 - Fixed the possibility to have a shader with a pre-refraction render queue and refraction enabled at the same time.
 - Fixed a migration issue with the rendering queue in ShaderGraph when upgrading to 10.x;
 - Fixed upside down XR occlusion mesh.
+- Fixed precision issue with the atmospheric fog.
 
 ### Changed
 - Combined occlusion meshes into one to reduce draw calls and state changes with XR single-pass.
