Worked on AvaloniaUI/Avalonia to enhance graphics adapter selection for Windows ARM64 devices, focusing on improving hardware acceleration opt-in and fallback clarity. Modified the ARM64 Adreno GPU blocklist to allow the full adapter list to reach the selection callback, enabling developers to opt into hardware acceleration where previously blocked. Addressed a latent IndexOutOfRange error that could occur when all adapters were filtered, increasing stability. Added warnings and documentation to inform users when software rendering (WARP) is used, clarifying CPU usage impacts and available workarounds. Utilized C#, OpenGL, and Angle, collaborating across the graphics stack to improve developer experience and system reliability.
