On an Intel Broadwell Dell laptop with Debian Sid/unstable and GNOME Wayland, updating Mesa from 20.0.1 to 20.0.2, mpv fails to play videos with the error below.

Using GNOME with X.Org it still works. The new iris driver shouldn’t be used by default, should it? So it’s different from issue #2220 (closed).
