Contributed to the MicrosoftDocs/sdk-api repository by addressing a bug related to Direct3D 12 subresource offset alignment. Focused on correcting the alignment requirement to ensure accurate data placement in memory, the work involved both code and documentation updates. By clarifying alignment rules and providing updated usage guidance, the changes reduced confusion for developers working with D3D12 resources. The approach combined API design expertise with detailed documentation, using Markdown to communicate technical requirements clearly. This targeted fix improved the reliability of memory management in Direct3D 12 and enhanced the overall developer experience by making alignment expectations explicit and traceable within the documentation.
