([UUM-73721](https://issuetracker.unity3d.com/issues/graphics-dot-copytexture-with-a-region-will-not-copy-readable-texture-data-for-compressed-formats-warnings-are-thrown-when-copying-compressed-texture-regions)) - HDRP: Fixed graphical issue when resizing Reflection Probe sizes on macOS ([UUM-71467](https://issuetracker.unity3d.com/issues/rendering-artefacts-appear-in-the-editor-when-modifying-the-reflection-probe-box-size)) - IL2CPP: Fix incremental GC issue when using multidimensional arrays and full generic sharing.
