Hi! After the upgrade to 21.10 I can no longer play video if I have vdpau set as my output driver. Any ideas?

I'm using SMplayer with the mpv multimedia engine. Trying to use vdpau as my output driver. If I change the output driver to libmpv the video plays fine. Changing it back to vdpau makes the screen go black. Audio plays fine either way.

I'm not sure what other information you need but please let me know anything I can output to make this easier to diagnose. Thank you for any help anyone can give!
