On an RTX 4060 (Ada, driver 617.42) the optimized link of a pipeline built from libraries loses the device (VK_ERROR_DEVICE_LOST) as soon as it is bound, which fails agc_driver_pixel_valid_mask in 16 of 20 runs. With APS5_NO_PIPELINE_LTO=1 it passes 20 of 20. Reporters see the same loss on an Ampere card with a depth attachment; two Blackwell cards do not lose it. A device whose driver is VK_DRIVER_ID_NVIDIA_PROPRIETARY keeps the fast-linked pipeline and no longer queues the link-time-optimized relink. Other drivers are unchanged.
