when I started my debian 11 system i noticed, that the thunderbird snap was suddenly using X11 instead of wayland. I noticed it because I have a xeyes running and it was reacting to the mouse position.
So i checked and disconnected thunderbird from the slot:
$ snap connections thunderbird ... Interface Plug Slot Notes wayland thunderbird:wayland :wayland - x11 thunderbird:x11 - -
Restarting thunderbird did not change anything. xeyes still gets the input from thunderbird.
In the end I want to run thunderbird again on wayland, but the more important issue is that the snap should not have been able to communicate with X11. I think this should not happen. I want to prevent the apps from accessing X11.
Thunderbird snap version installed: 102.0.1-2 (228) 105MB -
This is inside a gnome wayland user session.
