Bug Description

This was a fresh install of the daily image ubuntu mate downloaded on 4/2/2022.
Installed on btrfs, third party software enabled, nvidia driver set to on-demand mode.
Pretty much the first command I ran after install, intending to watch a twitch stream, while setting things up.

Just to note, this is not unique to streamed videos. I am also getting a segfault on local videos.

As a workaround for anyone running into this:
switching to vulkan drivers by adding
gpu-api=vulkan
to my mpv.conf file has fixed this for me in the mean time.

The offending library seems to be specific to the Nvidia driver. I only assume it's Nvidia version 510.

affects:	mpv (Ubuntu) → nvidia-graphics-drivers-510 (Ubuntu)
