Research direction
Run the reported mpv command with the linked sample image, then inspect the linked log and compare VAAPI decoding with --vo=gpu rendering. The issue provides no source file or test entry point, so trace the YUYV decoded-image path from the reproduction. Done means the sample renders correctly instead of showing a blue screen.
