The official source reports this update: b10677: vulkan: fix missing view-alias dependencies in ggml_vk_graph_optimize. vulkan: fix missing view-alias dependencies in ggml_vk_graph_optimize ( #27812 ) vulkan: fix missing view-alias dependencies in ggml_vk_graph_optimize is_src_of doesn't treat two views of one tensor as dependent, so the optimizer reorders nodes across aliased reads and writes. Result: silently wrong tokens under greedy decoding, different output on every server start, and invalid speculative-decoding acceptance, with nothing logged. Hits Qwen3.8's recurrent state (and any model with view-aliased state) on AMD and NVIDIA Vulkan. CUDA is clean.
