Thanks, that was it! Switching back to exa makes mpv VO [gpu] work
again for me.

With glamor, I see nothing (black screen) when switching to the mpv

I used:
# cat /etc/X11/xorg.conf.d/20-radeon.conf
Section "Device"
        Identifier  "Radeon"
        Driver "radeon"
#       Option "AccelMethod" "glamor"
        Option "AccelMethod" "exa"
