I cannot reproduce your problem and neither find a problem in the code.
Running "env -u DISPLAY ubuntu-bug -w apport" on a fresh Ubuntu 22.04
installation (with GNOME and wayland) opens apport-gtk correctly.
Neither killing Xwayland nor only setting WAYLAND_DISPLAY by running
"env -i WAYLAND_DISPLAY=wayland-0 ubuntu-bug -w apport" did change
anything (note: apport-gtk crashed in the latter case, but it was
called).
Supporting WAYLAND_DISPLAY as alternative was implemented in bug
#1418766 long time ago.
Can you reproduce your problem? What environment are you in?

Title:
ubuntu-bug won't show GUI window in pure wayland-sessions
Status in apport package in Ubuntu:
Incomplete
Bug description:
In case only `WAYLAND_DISPLAY` env variable is set (but no `DISPLAY`
as XWayland is disabled), ubuntu-bug won't show its window, even
though GTK will use the Wayland backend.
Test case, in an Ubuntu wayland session:
- Run:
env -u DISPLAY ubuntu-bug -w apport

So, ubuntu-bug should both consider `DISPLAY` and `WAYLAND_DISPLAY` to
be enough to use a graphical session.
