Replace the texture-shaped RGB24 output with a linear raw buffer and keep its packing, damage translation, and buffer copies inside the RGB24 effect. Benchmark full-frame native and packed processing and retain the faster path for each source format. Preserve logical damage rectangles for client updates and alternating framebuffer repair. Return compute outputs to COMMON for COPY queue handoff and refresh cached framebuffer sizes when switching packed and native layouts.
