 ### Fixed
 - Fixed GC allocations from XR occlusion mesh when using multipass.
 - Fixed XR depth copy when using MSAA.
+- Fixed resize IES when already baked in the Atlas 1299233
 - Fixed after post process custom pass scale issue when dynamic resolution is enabled (case 1299194).
 - Fixed an issue with light intensity prefab override application not visible in the inspector (case 1299563).
 - Fixed Undo/Redo instability of light temperature.
