You only need mpv bw36x36_nv12.avi --no-config --vo=gpu-next --gpu-api=vulkan to reproduce, works fine with vulkan on vo_gpu.

Vulkan doesn't support rgb32f as a fbo-format. You need to set fbo-format=rgba32f

thanks for the info. while stating facts is never wrong. does this change anything related to the topic? i got the same result. the mpv.conf was only added for preproduction in case i missed something.
