 - Fixed SSGI texture allocation when not using the RenderGraph.
 - Fixed NullReference Exception when setting Max Shadows On Screen to 0 in the HDRP asset.
 - Fixed issue with saving some quality settings in volume overrides  (case 1293747)
+- Fixed issue where some ShaderGraph generated shaders were not SRP compatible because of UnityPerMaterial cbuffer layout mismatches [1292501] (https://issuetracker.unity3d.com/issues/a2-some-translucent-plus-alphaclipping-shadergraphs-are-not-srp-batcher-compatible)
 
 ### Changed
