Aug 1, 2025Monthly summary for 2025-08 (google/filament): Delivered critical Vulkan and EGL backend improvements with a focus on texture support, memory safety, and stability. Key features expanded texture format support for ETC2_EAC_RGBA8 and ETC2_EAC_SRGBA8, enhancing texture conversion capabilities of the Vulkan backend. Major memory-management fixes were implemented for EGLAndroid AHardwareBuffer handling and external textures, addressing leak risks and lifecycle correctness. A memory corruption issue in VulkanExternalImageManager was resolved by adjusting lambda captures to ensure correct variable scope. Overall, these changes reduce OOM risk, improve rendering reliability, and demonstrate strong low-level engineering across Vulkan, EGL, and Android-specific paths.
