Any attempt to run cheese under Wayland fails: [guillaume@netchaiev ~]$ LC_ALL=C cheese Gdk-Message: 20:37:52.957: Error 71 (Protocol error) dispatching to Wayland display. A rapid search on internet show similar issues with Epiphany, dating from 2016, leading to this bug against mutter, which seems the actual faulty component: https://bugzilla.redhat.com/show_bug.cgi?id=1377287 https://gitlab.gnome.org/GNOME/mutter/issues/138 As advised in the redhat bug, exporting GDK_BACKEND=11 before running cheese is enough to fix the problem. And the problem doesn't exist under cauldron.

Cheese works fine for me in Sway (the only problem I have with Epiphany is that I can't get the sound to work). I know that a lot of Wayland programs have problems in GNOME Wayland (mostly due to GNOME's refusal to implement the xdg_decoration protocol, but there are also various other problems) and give warnings or errors if you try to use them in GNOME, but it's odd for even GNOME programs not to work in GNOME.

Seems Mageia 7 needs an update of Mutter (and then gnome-shell + extensions) to fix this.
