opp_env version: 1545882
OS: Ubuntu 25.04 (GNOME + Wayland)

Running to following command:

opp_env run inet-4.5 --init -w inet-workspace --install --no-isolated --build-modes=release --options=inet:full --chdir \
   -c 'cd inet-4.5.*/showcases/emulation/babel && sudo setcap cap_sys_admin=ep $(which opp_run_release) && inet'

...results in the following:

The application can be closed with File/Exit.

It works in isolated mode.
Workaround: add QT_QPA_PLATFORM=xcb before the inet command:

opp_env run inet-4.5 --init -w inet-workspace --install --no-isolated --build-modes=release --options=inet:full --chdir \
   -c 'cd inet-4.5.*/showcases/emulation/babel && sudo setcap cap_sys_admin=ep $(which opp_run_release) && QT_QPA_PLATFORM=xcb inet'
