Status changed to 'Confirmed' because the bug affects multiple users.

This is probably either a bug in the GL code paths of clutter-gst, or gstreamer-vaapi.

I don't suppose 'mpv' works for you with DVDs?

While mpv isn't that suitable for dvd (dev's don't care about), it does
work ok with vaapi in wayland.
Ex. (currently muddling thru the new changes that you'll see in 0.28, a
bit of a pita. Have gotten  -
window deco but no vaapi
