Could be related to intel/intel-vaapi-driver#566 not being merged yet (if you have an Intel GPU), in which case #7916 might help.

I'm using an AMD iGPU as wlroots render device, so this may not be related?

Might be unrelated but that's a bit weird.

vaapi is used on amd as well, although dmabuf-wayland should work for yuv420p even in the absence of vaapi but you should try running sway with sway -Dlegacy-wl-drm.

Also mpv logs would be more useful here, mpv --no-config --vo=dmabuf-wayland --log-file=mpvsucks.log [video]

sway -Dlegacy-wl-drm indeed solved my problem, dmabuf-wayland works as expected now
