gtk: DVD menu highlights don't line up with menus
The menu highlights in DVDs don't line up with the menus themselves and are shifted to the right.
Press "M" a bunch of times to get back to the menu in totem: http://samples.mplayerhq.hu/sub/DVD-short/red-will-not-display-subtitle.iso
Reproducible with the preview version of totem which uses GStreamer 1.20.0 and gtkglsink:
flatpak install --user https://flathub.org/beta-repo/appstream/org.gnome.Totem.Devel.flatpakref
Doesn't happen with the stable version of totem which uses GStreamer 1.20.0 and clutter-gst/clutter-gtk: https://flathub.org/apps/details/org.gnome.Totem
Any pointers as to where to look @thaytan ?
