mpv fails after multiple ports updated

After recent mesa,, ffmpeg, and vukan updates, mpv no longer works on my
system running head (n286199-96256587b06c), mpv no longer works. The
display flickers back and forth between frames and generates
continual errors of:
[vo/gpu-next/libplacebo] vkQueueSubmit2: VK_ERROR_UNKNOWN
(../src/vulkan/command.c:533)
I tried playing with vlc and it plays correctly, but with lots of error
messages:

From that point, the video plays properly.

It is not obvious to me which port is hte source of hte error. is failing.
The failure started within the past two weeks.

Has anyone else seen this? I really don't want to submit a bug report until
I am reasonable sure that I am submitting to the right place.
