Shell freezes when starting screencast with vaapi encoder on same GPU
gnome-shell 3.32.2+6+g8b987408 Wayland mode, scaled framebuffers active. gstreamer-vaapi 1.16.0
After launching org.gnome.Shell.Screencast with pipeline like vaapih264enc ! h264parse ! matroskamux
(e.g. with help of https://github.com/EasyScreenCast/EasyScreenCast) shell freezes: cursor doesn't animate/move, no reaction to power buttons. But systemd-logind is logging button events.
Same with vaapih265enc. Any software codec works ok.
