Also found an extra problem with this test case. Both vaapi and vdpau are
dropping lots of frames on it.

Could you try:
mpv --vo=vaapi --hwdec=vaapi https://www.youtube.com/watch?v=LXb3EKWsInQ
mpv --vo=vdpau --hwdec=vdpau https://www.youtube.com/watch?v=LXb3EKWsInQ

Then resize down the window.
This reproduces the jagginess and also introduces constant stuttering.

Let me know if you can reproduce, I'm at work now but I can provide captures
and logs when I come home if needed.
