> All apps default to Weston window when launched
This is somewhat intended. Graphical toolkits default to using Wayland
over X11. Even if $WAYLAND_DISPLAY is not set, the default `wayland-0`
name will be attempted and if that exists it will be used, regardless of
whether it's a nested compositor or not.
So if weston uses `wayland-0` as a socket name, applications will use it.
Because weston is often used as a non-primary display server, starting from
version 10 it now uses a different default socket name, `wayland-1`, so that
this "bug" does not happen anymore:
https://gitlab.freedesktop.org/wayland/weston/-/commit/ae69381b6eb43ab63992906d1bf29ffd2b4df10d
Ubuntu 22.04 uses weston version 9 so the change would have to be
backported. But I don't know if it is an acceptable change, as it might
break scripts that rely on the default socket name being `wayland-0`.
For this reason I've marked the bug as "Opinion: Doesn't fit with the
project, but can be discussed."
You can address this problem yourself by starting weston with the
`--socket=NAME` parameter, using any NAME you like. When starting
programs from within the weston UI nothing will change; when starting
programs from outside of weston instead, you can set the WAYLAND_DISPLAY
env variable to the same socket name and only that specific program will
display inside weston.
